Description Karsten Thoms CLA 2011-07-05 06:33:01 EDT 
I am trying to set up a Tycho based build for Xtext 2.0 projects and finally running into a NPE in EclipseLogAppender. I did not find that appender class, so I cannot give more details then the stack trace.

I am using the itemis Indigo distribution.
