Description

When an async aggregate's delegate descriptor is a Jms Service Descriptor the deployment fails with:

Caused by: java.lang.ClassCastException: org.apache.uima.resource.impl.CustomResourceSpecifier_impl incompatible with org.apache.uima.resource.ResourceCreationSpecifier

The code in BaseAnalysisEngineController.setupName() is blindly casting delegate's resource specifier to ResourceCreationSpecifier. If the delegate descriptor happens to be a Jms Service Descriptor the cast fails since the specifier is of type CustomResourceSpecifier.

This bug is triggered if an aggregate is async.

Besides fixing the bug add a new JUnit test to cover this scenario
