Feb 14, 2019 9:51:02 AM org.apache.uima.ducc.test.randomsleep.FixedSleepCR
getNext(328)
INFO: getNext
org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator class
org.apache.uima.ducc.CasHelper requires Type org.apache.uima.ducc.Workitem,
which was not found in the CAS.

To make things worse the above exception is ignored by JD code and the job
continues until completion giving a false sense of positive completion. The
Duccmon shows no errors.
Two fixed needed:
1) Address the missing Workitem type in the cas
2) Improve error handling to detect an exception and cancel a job
