Jikes license



As many of you know, Jikes has now been released under the new
IBM Public License Version 1.0.  I have seen this new license discussed
on Debian-Legal in recent weeks, but the end decision seemed to me
inconclusive on whether or not this qualified as DFSG-free.

The subject is no longer merely academic - since Jikes is now using this
license, and will presumably be included in the forthcoming 2.2 release,
I would like to know whether to move Jikes from non-free to main.

I am not a lawyer, and have not spent nearly sufficient time comparing
and contrasting this license with the previous version to give a
well-informed opinion on the question.  I'd like some guidance here.

Thanks.

=====================================================

              IBM PUBLIC LICENSE VERSION 1.0 - JIKES COMPILER

   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS IBM
   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION
OF
   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

  1. DEFINITIONS

   "Contribution" means:
    a. in the case of International Business Machines Corporation
       ("IBM"), the Original Program, and
    b. in the case of each Contributor,
         i. changes to the Program, and
        ii. additions to the Program;
       where such changes and/or additions to the Program originate from

       and are distributed by that particular Contributor. A
Contribution
       'originates' from a Contributor if it was added to the Program by

       such Contributor itself or anyone acting on such Contributor's
       behalf. Contributions do not include additions to the Program
       which: (i) are separate modules of software distributed in
       conjunction with the Program under their own license agreement,
       and (ii) are not derivative works of the Program.

   "Contributor" means IBM and any other entity that distributes the
   Program.

   "Licensed Patents " mean patent claims licensable by a Contributor
   which are necessarily infringed by the use or sale of its
Contribution
   alone or when combined with the Program.

   "Original Program" means the original version of the software
   accompanying this Agreement as released by IBM, including source
code,
   object code and documentation, if any.

   "Program" means the Original Program and Contributions.

   "Recipient" means anyone who receives the Program under this
   Agreement, including all Contributors.

  2. GRANT OF RIGHTS

    a. Subject to the terms of this Agreement, each Contributor hereby
       grants Recipient a non-exclusive, worldwide, royalty-free
       copyright license to reproduce, prepare derivative works of,
       publicly display, publicly perform, distribute and sublicense the

       Contribution of such Contributor, if any, and such derivative
       works, in source code and object code form.
    b. Subject to the terms of this Agreement, each Contributor hereby
       grants Recipient a non-exclusive, worldwide, royalty-free patent
       license under Licensed Patents to make, use, sell, offer to sell,

       import and otherwise transfer the Contribution of such
       Contributor, if any, in source code and object code form. This
       patent license shall apply to the combination of the Contribution

       and the Program if, at the time the Contribution is added by the
       Contributor, such addition of the Contribution causes such
       combination to be covered by the Licensed Patents. The patent
       license shall not apply to any other combinations which include
       the Contribution. No hardware per se is licensed hereunder.
    c. Recipient understands that although each Contributor grants the
       licenses to its Contributions set forth herein, no assurances are

       provided by any Contributor that the Program does not infringe
the
       patent or other intellectual property rights of any other entity.

       Each Contributor disclaims any liability to Recipient for claims
       brought by any other entity based on infringement of intellectual

       property rights or otherwise. As a condition to exercising the
       rights and licenses granted hereunder, each Recipient hereby
       assumes sole responsibility to secure any other intellectual
       property rights needed, if any. For example, if a third party
       patent license is required to allow Recipient to distribute the
       Program, it is Recipient's responsibility to acquire that license

       before distributing the Program.
    d. Each Contributor represents that to its knowledge it has
       sufficient copyright rights in its Contribution, if any, to grant

       the copyright license set forth in this Agreement.

  3. REQUIREMENTS

   A Contributor may choose to distribute the Program in object code
form
   under its own license agreement, provided that:
    a. it complies with the terms and conditions of this Agreement; and
    b. its license agreement:
         i. effectively disclaims on behalf of all Contributors all
            warranties and conditions, express and implied, including
            warranties or conditions of title and non-infringement, and
            implied warranties or conditions of merchantability and
            fitness for a particular purpose;
        ii. effectively excludes on behalf of all Contributors all
            liability for damages, including direct, indirect, special,
            incidental and consequential damages, such as lost profits;
        iii. states that any provisions which differ from this Agreement

            are offered by that Contributor alone and not by any other
            party; and
        iv. states that source code for the Program is available from
            such Contributor, and informs licensees how to obtain it in
a
            reasonable manner on or through a medium customarily used
for
            software exchange.

   When the Program is made available in source code form:
    a. it must be made available under this Agreement; and
    b. a copy of this Agreement must be included with each copy of the
       Program.

   Each Contributor must include the following in a conspicuous location

   in the Program:

     Copyright (C) 1996, 1999 International Business Machines
     Corporation and others. All Rights Reserved.

   In addition, each Contributor must identify itself as the originator
   of its Contribution, if any, in a manner that reasonably allows
   subsequent Recipients to identify the originator of the Contribution.


  4. COMMERCIAL DISTRIBUTION

   Commercial distributors of software may accept certain
   responsibilities with respect to end users, business partners and the

   like. While this license is intended to facilitate the commercial use

   of the Program, the Contributor who includes the Program in a
   commercial product offering should do so in a manner which does not
   create potential liability for other Contributors. Therefore, if a
   Contributor includes the Program in a commercial product offering,
   such Contributor ("Commercial Contributor") hereby agrees to defend
   and indemnify every other Contributor ("Indemnified Contributor")
   against any losses, damages and costs (collectively "Losses") arising

   from claims, lawsuits and other legal actions brought by a third
party
   against the Indemnified Contributor to the extent caused by the acts
   or omissions of such Commercial Contributor in connection with its
   distribution of the Program in a commercial product offering. The
   obligations in this section do not apply to any claims or Losses
   relating to any actual or alleged intellectual property infringement.

   In order to qualify, an Indemnified Contributor must: a) promptly
   notify the Commercial Contributor in writing of such claim, and b)
   allow the Commercial Contributor to control, and cooperate with the
   Commercial Contributor in, the defense and any related settlement
   negotiations. The Indemnified Contributor may participate in any such

   claim at its own expense.

   For example, a Contributor might include the Program in a commercial
   product offering, Product X. That Contributor is then a Commercial
   Contributor. If that Commercial Contributor then makes performance
   claims, or offers warranties related to Product X, those performance
   claims and warranties are such Commercial Contributor's
responsibility
   alone. Under this section, the Commercial Contributor would have to
   defend claims against the other Contributors related to those
   performance claims and warranties, and if a court requires any other
   Contributor to pay any damages as a result, the Commercial
Contributor
   must pay those damages.

  5. NO WARRANTY

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY

   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
   responsible for determining the appropriateness of using and
   distributing the Program and assumes all risks associated with its
   exercise of rights under this Agreement, including but not limited to

   the risks and costs of program errors, compliance with applicable
   laws, damage to or loss of data, programs or equipment, and
   unavailability or interruption of operations.

  6. DISCLAIMER OF LIABILITY

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT
NOR
   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF

   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

  7. GENERAL

   If any provision of this Agreement is invalid or unenforceable under
   applicable law, it shall not affect the validity or enforceability of

   the remainder of the terms of this Agreement, and without further
   action by the parties hereto, such provision shall be reformed to the

   minimum extent necessary to make such provision valid and
enforceable.

   If Recipient institutes patent litigation against a Contributor with
   respect to a patent applicable to software (including a cross-claim
or
   counterclaim in a lawsuit), then any patent licenses granted by that
   Contributor to such Recipient under this Agreement shall terminate as

   of the date such litigation is filed. In addition, if Recipient
   institutes patent litigation against any entity (including a
   cross-claim or counterclaim in a lawsuit) alleging that the Program
   itself (excluding combinations of the Program with other software or
   hardware) infringes such Recipient's patent(s), then such Recipient's

   rights granted under Section 2(b) shall terminate as of the date such

   litigation is filed.

   All Recipient's rights under this Agreement shall terminate if it
   fails to comply with any of the material terms or conditions of this
   Agreement and does not cure such failure in a reasonable period of
   time after becoming aware of such noncompliance. If all Recipient's
   rights under this Agreement terminate, Recipient agrees to cease use
   and distribution of the Program as soon as reasonably practicable.
   However, Recipient's obligations under this Agreement and any
licenses
   granted by Recipient relating to the Program shall continue and
   survive.

   IBM may publish new versions (including revisions) of this Agreement
   from time to time. Each new version of the Agreement will be given a
   distinguishing version number. The Program (including Contributions)
   may always be distributed subject to the version of the Agreement
   under which it was received. In addition, after a new version of the
   Agreement is published, Contributor may elect to distribute the
   Program (including its Contributions) under the new version. No one
   other than IBM has the right to modify this Agreement. Except as
   expressly stated in Sections 2(a) and 2(b) above, Recipient receives
   no rights or licenses to the intellectual property of any Contributor

   under this Agreement, whether expressly, by implication, estoppel or
   otherwise. All rights in the Program not expressly granted under this

   Agreement are reserved.

   This Agreement is governed by the laws of the State of New York and
   the intellectual property laws of the United States of America. No
   party to this Agreement will bring a legal action under this
Agreement
   more than one year after the cause of action arose. Each party waives

   its rights to a jury trial in any resulting litigation.
