Hello,

 

After updating our target platform to Xtext 2.10 / Eclipse Neon I am getting the following error very often when testing our plugins in a runtime Eclipse, apparently when executing tasks which are not directly related to Xtext itself (e.g. creating a new CDT project).

This seems to be a dependency injection issue of some sort. Any pointers on how these exceptions can be debugged? I tried re-creating the launch configuration without success.
