[jira] Created: (UIMA-1727) CPM doesnt validate registered
CallbackListener references
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.

[jira] Closed: (UIMA-1727) CPM doesnt validate registered
CallbackListener references

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.
