Hello,

I am trying to deploy a bundle in Felix 3.2.2. Some dependencies seem to be 
unmet, but what I get is this:

ERROR: Bundle ***[36] Error starting file:/***.jar

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
