1 Answer 1

As far as MESSAGE Keybinding conflicts goes:

This is a notified Eclipse bug, which appears to be still with us. Not sure what the jface has to do with it really. Apparently re-starting solves the problem.

As for java.lang.NullPointerException That could be absolutely anything to do with your own particular SDK.

If it's Android then it is most likely the irritating fact that when you attempt to run/debug a project, the entry which names the project that you are running sets itself to blank every now and then!

Look in the project run/debug specifications.
