Jerry Cwiklik updated UIMA-1630:
--------------------------------
Description:
There seems to be a synchronization problem in BaseAnalysisEngineController
leading to the exception like this:
Caused by: java.lang.IndexOutOfBoundsException: Index: 2, Size: 0

The aggregate controller attempts to stop its colocated delegates and fails
with IndexOutOfBounds. It looks like one thread is trying to stop, while
another is cleaning up a HashMap. Need to synchronize these activities.
