I'm not sure if this is related to Proxy creation or not. I do believe
there could be some issues with that. However, I think this issue is
more related to dynamic imports...that's just a guess.
This still needs to be tested on 4.0.x, though...and I'll probably only
ever get to the bottom of it if we can get me to reproduce it.

Hi Richard,
Version of Felix and Karaf used are :
Karaf
Karaf version 2.2.7
Karaf home
/Users/chmoulli/MyApplications/apache-karaf-2.2.7
Karaf base
/Users/chmoulli/MyApplications/apache-karaf-2.2.7
OSGi Framework org.apache.felix.framework - 3.0.9
JVM
Java Virtual Machine Java HotSpot(TM) 64-Bit Server VM version
20.8-b03-424
Version 1.6.0_33
In our scenario, we use weld-osgi to create for each bundle a CDI
container. The CDI container depending on the CDI annotations (@Inject,
...) discovered in the bundle will instantiate some new beans and add them
to the class loader. In my case the bundle A = example has a reference to a
class exported by a bundle B (= CdiCamelContext) and this class
CdiCamelContext is created using java.lang.reflect.Proxy.**newProxyInstance().
Remark, this class CdiCamelContext extends a CamelContext class exported by
another bundle = C. The package B imports well the packages from C.
Regards,
Charles

Hi,
What could be the reason why we get a NPE at the followoing line
Not sure. A similar issue was reported in:
https://issues.apache.org/**jira/browse/FELIX-3003<https://issues.apache.org/jira/browse/FELIX-3003>
Can you reproduce this? That would make it a lot easier to track down.
It is also not clear which version of the framework you are using...it
doesn't appear to be 4.0.x.
