CCSv6.1.1: "Problem Occurred" dialog box with java.lang.NullPointerException popping up every once and a while

Hello,

Every once in a while CCS pops up a Problem Occurred" dialog box with a java.lang.NullPointerException (shown below).  Has anyone else been having this issue? It's often enough to be annoying.

    With CCS 6.1.1 under Linux have sometimes seen this when starting a debug session. Doesn't seem to have caused a problem, so have just been closing the dialog.

    In the most recent case, the following appeared in the Eclipse log:

    !ENTRY org.eclipse.ui.workbench 4 2 2015-11-03 15:09:25.704
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

    this issue kept popping up for me recently on Windows 7. I have many projects opened in my workspace and I knew one of them was causing it. I removed some projects and the issue went away. The cause for me was a corrupted project.

    I have 14 projects in my workspace, so it may be that one of them is corrupt.

    When i first got the error, it was after i was mucking around with one of my projects so i knew that was the culprit. I should have debugged the issue but i just got so annoyed at the message that i deleted it to get rid of it. I was doing something weird with the project (experimenting with something) but I can't remember what it was now.

    I think the java.lang.NullPointerException reported in the dialog could happen for a number of reasons (in my case it seemed related to the display of the Memory View when starting a debug session). 

    Suggest that you use Help -> CCS Support and View the Eclipse Log to see if the Eclipse Log gives more details about what caused the java.lang.NullPointerException.

    Here's what the log shows:

    Was that the only entry in the log?

    That entry reports a java.nio.channels.ClosedByInterruptException, as opposed to the java.lang.NullPointerException which was reported on the "Problem Occurred" dialog box.

    The Eclipse log seems to get written to over time, and looking at an example Eclipse log from CCS 6.1.1 there are some reports of a java.lang.NullPointerException at times which didn't result in a "Problem Occurred" dialog box.

    I don't understand Eclipse well enough to know if the "Problem Occurred" dialog boxes which appear are really a sign of a problem of not.

    Not sure what else to suggest, apart from does the"Problem Occurred" dialog box appear "at random" or when a specific action is attempted?

    With CCS 6.1.1 under Linux have sometimes seen this when starting a debug session. Doesn't seem to have caused a problem, so have just been closing the dialog.

    In the most recent case, the following appeared in the Eclipse log:

    Edit 6 Nov 2015: The CCS 6.1.1 problem in this post was reported in the separate thread https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/467874, and bug SDSCM00052465 raised.

    Have now seen the "Problem Occurred" dialog box with java.lang.NullPointerException being displayed when part of the CCS 6.1.1 GUI under Linux is not being displayed correctly.

    Sequence was:

    1) Had been using the Memory Browser view successfully during debug sessions, with Continuous Refresh selected as in the following screen shot:

    2) Terminated the debug session and shutdown CCS.

    3) Restarted CCS and attempted to start the same debug session again. The "Problem Occurred" dialog box with java.lang.NullPointerException was displayed, and I noticed the Memory Browser view wasn't being drawn correctly, in that the "Continuous Refresh" control (and some others) were no longer displayed in the Memory Browser:

    Around the time the  "Problem Occurred" dialog box with java.lang.NullPointerException was displayed, the following was written to the Eclipse log, which is NullPointerException in the MemoryView:

    Can someone from TI see if they can repeat this java.lang.NullPointerException with the Memory Browser view?

    Guru 20045 points

    There were many entries in the the log and they were all the same.  I copied the log in to excel and filtered by the line containing the  time (see below).

    I will immediately check the log the next time it occurs.

    Thanks,

    There were many entries in the the log and they were all the same.

    Based upon the Java stack backtrace reported for the java.nio.channels.ClosedByInterruptException in your Eclipse log, the exception appears to have occurred when Eclipse was parsing the source code in the workspace.

    Are you seeing any problems with the Eclipse indexer / symbol navigation not working?

    Other than https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/465057, I haven't noticed any issues with the indexer.   However, that doesn't mean there isn't an issue with Eclipse indexer / symbol navigation.

    That indexer problem thread was marked as resolved on November 3 2015, whereas the java.nio.channels.ClosedByInterruptException exceptions listed in your Eclipse log were all dated November 2 2015. Therefore, the fix to the indexer problem may have stopped the java.nio.channels.ClosedByInterruptException exceptions.

    The question for this thread is does the "Problem Occurred" dialog box with java.lang.NullPointerException get displayed after a specific action in CCS, or is it a "random" event?

    I haven't figured that out yet. I will continue to monitor it and once I get some more information I will post it to this thread.

    Thanks,
