The problem is that the EJB container has published an object in JNDI
which upon looked up is causing some code to be generated using the
caller's class loader. Since the generated code depends on EJB container
classes, it is failing as the calling bundle does not have access to EJB
container classes. Not sure if they could use a different class loader
to generate and load the proxy class as Weld does. File a bug to this
effect.
As a work around, could you try adding DynamicImport-Package:
com.sun.ejb.* to your bundle and see if that solves the problem?
Thanks,
Sahoo
