I have traced the problem to

whereas AspectJ expects it to at least return an empty enumeration - hence the NPE.

Jesper S. Møller commented on JBRULES-3122:
-------------------------------------------
This is also a BIG problem for Grails 2 since it uses the "springloaded" agent
which also assumes that PackageClassLoader adheres to the API spec. Returning null is NOT
an option!
Returning an empty Enumerator is IMHO a better fix than calling parent, since
getResource() consistently returns null.

I have traced the problem to
org.drools.rule.JavaDialectRuntimeData$PackageClassLoader.getResources. This returns null
whereas AspectJ expects it to at least return an empty enumeration - hence the NPE.

Jesper S. Møller commented on JBRULES-3122:
-------------------------------------------
I found another place where a null is being returned from a Drools class loader, this time
it is the CompositeClassLoader in knowledge-api. For the life of me, I cannot find the
tests for it, but I've added a pull request for it as well.
