Problem is fixed for the command that actually have shortkeys. If we add new shortkeys, the handler dealing with the commands will have to be verified as well.
The issue still happens, sometimes when short key for "go into" or open review item eclipse.buildId=M20110210-1200 java.version=1.6.0_26 java.vendor=Sun Microsystems Inc.

This error is a different one than what was happening. We should open a new bug for this
The user scenario is the same, The scenario shall work for all key combinations and shall have no exceptions, this issue is not dependent on exception signatures.
What I mean is that the exception that is generated is different than the one that was generated before. So the initial problem is fixed, but there are still issues with the shortcuts
- Initial description fix with Bug 362259 - The issue with short key for "go into" fixed with this bug release
Duplication *** This bug has been marked as a duplicate of bug 362259 ***
