Description Rick Moseley 2007-06-01 13:53:28 UTC

After opening a debug window and then running an executable, continuing the
execution of the executed process and then stopping it causes a backtrace like this:

java.lang.NullPointerException
   at frysk.gui.srcwin.SourceWindow.populateStackBrowser(SourceWindow.java:706)
   at frysk.gui.srcwin.SourceWindow$LockObserver$38.run(SourceWindow.java:3222)

Comment 1 Rick Moseley 2007-06-01 16:43:34 UTC

Fixed in CVS head with changes to SourceWindow.java.  The DebugProcess object
was not being checked for nullness before trying to get the WatchList.
