Description Benjamin Schwertfeger CLA 2010-08-06 05:29:25 EDT 
Annotations like search result marker does not have a text. The ProblemHover class will exit with a NPE then and not work any more, until you reopen the editor.

1. Open any xtext editor, generated or original editor for grammars.
2. Write something bad and hover over the error marker. The message is shown.
3. Search for one word inside this file by File Search
4. See the yellow arrows beside the line with matches. Hover over them.
5. No Message is shown
6. Hover over the Errors in this file again. No Message is shown also.

An Error is also printed to the ErrorLog.

Check for existence of message before trimming it.

The message should be checked for null, before it is trimmed.
