NullPointerException when trying to load class
Hi,
We are using Felix 3.2.2 and sometimes following NPE occurs when Framework
tries to load a class during Bundle startup:
Caused by: java.lang.Exception: org.osgi.framework.BundleException:
Activator start error in bundle XXX [167].

I had a look at Felix sources and found that some ContextPath object seems
to be null...
Does anyone already got this error?
Thank you
Olivier

Bummer.
This area has changed a bit. You could try to reproduce it with the
latest 3.3.0 snapshot from the Maven repo snapshot repo. I wouldn't
recommend really using the snapshot version unless you are purely in
development mode and are willing to live on the edge.

It's very hard for me to reproduce this problem, so I'm pretty sure I can't generate a working test case...
Sorry about that...

Not aware of it. Is this something that you can give me a working test case?
