-----------------------------------
Summary: UIMA-AS: NPE thrown when cleaning up C++ based service
Key: UIMA-5118
URL: https://issues.apache.org/jira/browse/UIMA-5118
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.9.0AS
NPE is thrown from BaseUIMAAsynchronousEngine_impl.undeploy()
line:
((AnalysisEngineController) ctrer).getControllerLatch().release();
when a controller is an instance of UimacppServiceController. This class
returns null from getControllerLatch() causing NPE in the uima-as client which
tries to clean up after processing.
Add check for null before attempting call to release().
