Summary: UIMA-AS: fix ClassCastException when delegate specifier
is CustomResourceSpecifier
Key: UIMA-5750
URL: https://issues.apache.org/jira/browse/UIMA-5750
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Affects Versions: 2.10.2AS
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.10.3AS
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 is an aggregate is async.
Besides fixing the bug add a new JUnit test to cover this scenario
