Let's imagine we base cocoon on spring. There was a discussion about including hibernate in cocoon and it failed (licensing). Spring being ASL 2.0 ships with hibernate library, even if not - it contains code that was compiled against hibernate interfaces. Wouldn't this be an issue?
Ouch. yes. Can you outline the dependencies more?
org.springframework.orm.hibernate org.springframework.orm.hibernate.support
The problem is that the distribution consists of :
- either single spring.jar that contains all
- or spring-XXX.jar where XXX is core, orm, aop and so on. you could drop whole spring-orm.jar but then you loose all support for any OR framework.
I am suprised of one fact: how can Spring be distributed with ASL 2.0 license if it is compiled against LGPL code (and redistributes this code in compiled form also)?
The ASF (well, some directors) believe that the LGPL is still viral for java code. This has never been tested in court, nor the FSF has publicly stated a clear opinion on the subject, so the ASF prefers to stay away from it.
Personally, I don't think there any problem in LGPL dependencies.
Are they in trouble or are we wrong?
Nobody is in trouble (unless the hibernate people go after them, which would be a pretty stupid thing to do anyway)

there are two issues here:
1) the LGPL stuff 2) the J2EE stuff
Both contain wording that makes some ASF directors uneasy. For example, the J2EE API state that *YOU* have to defend sun in case somebody files a patent complain because of the code you redistribute.
Jakarta was created to route around this issue for the servlet API, basically and no talking was able to modify Sun's position on that for the other APIs.
Look, if it was for me, I'd say "fuck it, let's use them and wait for them to cease and desist us, then we move it to slashdot".
but I seem to be in minority up there.
