Hi Andre,

I've been quite busy...sorry about the slow reply.

Isn't it possible for there to be a ConfigurationListener that is not 
registered by DS?

OK, sounds good.  I saw that the new patch was attached to the bug 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=285294

Thanks for doing that.  The patch will be addressed, but Holger probably 
has to do it, and I imagine  he has other items to deal with as well 
(just FYI).
