Debian[1]. I think it's in the java faq. And another point is that the license does not allow someone who use one of the tools from the jdk to use a replacement tool!.. I think I am outlaw ;-)
Are you refering to: 5.3.1.4 Can I use jdk1.2 while working with the free Java implementations?If it is so, I think it says that you cannot _contribute_ to a replacement _of java.* and sun.*_. That doesn't say you cannot _use_ them.
