Description Christoph Laeubrich CLA 2019-10-07 08:37:03 EDT 
org.eclipse.e4.ui.internal.workbench.ModelAssembler.processFragment(MModelFragments, MModelFragment, String, String, boolean) emits an error like this:

"Fragment from <x> of <Y> could not be validated and was not merged <Z>"

But does not include the actual error. So for any non trivial fragment.e4xmi the message is completely useless to the user as he has no idea whats wrong.

The use needs all details from the DiagnosticResult to get an idea whats going on.

Current Workaround is to attach a debugger and then extract the necessary information manually.
