Ivo Ladage - van Doorn commented on AMDATUOPENSOCIAL-193:
---------------------------------------------------------
After more analysis, it seems that the ClassCastException is caused by a
classloader mismatch; the org.w3c.dom.DOMImplementationSource class is loaded
by the bundle classloader and the bootstrap classloader.
The classloader used in org.w3c.dom.bootstrap.DOMImplementationRegistry to load
the com.sun.org.apache.xerces.internal.dom.DOMXSImplementationSourceImpl class
that implements this interface is loaded by the context classloader of the
current thread. But that classloader varies; sometimes its the felix framework
classloader, sometimes the bootstrap classloader.
Another error is that the integration test finishes even if i set a breakpoint
on the Guice.createInjector(Stage.PRODUCTION, modules) in
GuiceInjectorServletImpl. If the Guice injector has not finished injection,
Shindig is not yet started properly and so the integration test should not
start at all.
