If an aggregate uses the unsupported "include" instead of "import" a very very very obscure error message results

In converting a CPE descriptor to an aggregate descriptor I forgot to change one "<include ..." to "<import ...".
The docs indicate that include is not supported but the CDE error message was:

"ResourceInitializationException: The CasCreationUtils.createCas method was passed a collection containing an object of class org.apache.uima.collection.impl.metadata.cpe.CpeIncludeImpl, which is not supported."

Not very helpful!

The cvd reported a stack trace but still no clue as to what part of what file was in error:

org.apache.uima.tools.cvd.MainFrame.handleException(575): SEVERE: org.apache.uima.collection.impl.metadata.cpe.CpeIncludeImpl incompatible with org.apache.uima.resource.ResourceSpecifier
