Jerry Cwiklik closed UIMA-1727. ------------------------------- Resolution: Fixed Added a check for null to prevent adding bad references to the list of callback listeners. Also, before calling the registered listener code now checks for null reference. > CPM doesnt validate registered CallbackListener references > ----------------------------------------------------------- > > Key: UIMA-1727 > URL: https://issues.apache.org/jira/browse/UIMA-1727 > Project: UIMA > Issue Type: Bug > Components: Collection Processing > Reporter: Jerry Cwiklik > Assignee: Jerry Cwiklik > > The CPM uses a list of registered listeners to notify an application of > certain events. The application registers listeners with the CPM before it > starts the run. Apparently, the CPM doesnt validate a listener reference > provided by the application and blindly adds it a list. If the reference is > null, the NPE is thrown when trying to send notifications. Fix the code to > validate listener reference to prevent adding null references. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
