Hi,

the upload of libxpp3-java 1.1.3.4.O-4 to unstable fixes the following RC

It also fixes these policy compliance issues:
   * Move dependencies for clean target to Build-depends.
   * Update to policy version 3.8.0.1.
     - Describe patch management in README.source.
   * debian/copyright: Completed copyright information.

Thanks,
