Hello Richard,
many thanks for the quick reply. Replacing the jar did the job and the error didn't occur
again. I now get many " DEBUG: Candidate permutation failed due to a conflict
between imports; will try another if possible." outputs (in the code, this happens
after where the NRE used to be), and eventually resolving succeeds.
Just one more question: What is the intended release date for 3.3.0?
The ultimate release version will be 4.0 and it should hopefully be in
the next couple weeks. The snapshot should be good enough to use for
development purposes in the meantime.

Best Regards
Christoph

Hello,
I am trying to deploy a bundle in Felix 3.2.2. Some dependencies seem to be

What seems to be happening here is that an NPE is being thrown during the
assembly of an error message for an exception that is, usually, thrown and
catched (on line 132) and used for control flow (trying a different
permutation).
So I'm not even sure if resolving wouldn't work just fine if this NPE weren't
thrown (felix bug) or if our bundle structure has some very bad problem (in
which case the NPE is still a problem). Any suggestions?
This is repeatable? If so, could you try it on 3.3.0-SNAPSHOT (i.e., a trunk
build)? You can grab a distribution release from the Maven snapshot repo here:
https://repository.apache.org/content/groups/snapshots-group/org/apache/felix/org.apache.felix.main.distribution/3.3.0-SNAPSHOT/org.apache.felix.main.distribution-3.3.0-20110901.210822-19.tar.gz
If it still errors here, then help me reproduce the issue so I can get it fixed
before the next release...I did fix a bug like this, so it may be the same one.

Thanks in advance
