Christian, you've assigned this bug to the JDT (Java Development Tooling) project, APT (Annotation Processing Tooling) component.

I don't know what project this should go to, but it is surely not JDT/APT.  I'm going to reassign it to PDE.  In the future, when reporting bugs, it will be helpful if you can spend a bit more time deciding what project to assign a bug to.  thanks!

Marking as helpwanted as there are no committers actively working on the DS component.
