Description Patrick Chuong

During the initializatoin Job for the pin ViewIDCounterManager, calling IViewReference#getView(true) result in a nullpointer exception. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=331781#c29, for more detail. The current workaround is to call getView(false) and listen to partOpened to reset the title.

Note that the NPE does not happen when we call IViewReference#getView(true) but will eventually happen when we terminate a DSF-GDB launch.

I still can't reproduce this NPE, I am able to terminate the session without issue. I am wondering whether this is related to linux or not. I'll need to setup my linux VM and give it a try.

For me (on Linux) it happens all the time.
I can try it on Windows tonight.
