I've run into a problem like this before and I don't know why OSGI
requires breaking the JDK. I forget the solution, but I'm stuck
until I find one.
...
Module amx-j2ee-impl has a dependency on module amx-core-impl, and
calls getSelf(J2EEServer.class). Method getSelf() is in a superclass
which is found in the amx-core-impl module. The generated proxy uses
a handler defined in the amx-core module.
The calling code looks like this:
import javax.management.ObjectName; <=== imports the problem class
...
J2EEServer selfProxy = getSelf(J2EEServer.class); <== call superclass
method in another module
ObjectName test = selfProxy.objectName(); <== ClassNotFoundException
The proxy method objectName() returns a javax.management.ObjectName, a
standard class in the JDK.
Yet, I get a NoClassDefFoundError. This seems like a bug to me, and I
don't know how to fix it.
