Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Affects Versions: 2.4.0AS
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Priority: Minor
Fix For: 2.4.1AS
When running uima-as with a logger configured at FINE or FINEST,
ConcurrentModificationException is thrown from one of the methods which is only
called when log level > INFO. The dumpPendingReplyList() method iterates over a
list which is concurrently being updated by another thread. Synchronize access
to the list to prevent the exception.
