Koen Aers commented on GPD-271:
-------------------------------

This exception is thrown in code that is internal to Eclipse. I was able to reproduce it but I have the impression that it is not particularly due to a bug or misuse of the Eclipse API in the designer. I want to try and isolate the problem but I will not be able to do it before the release of 3.1.6. As the issue has no impact on the correctness, i.e. the deployment occurs without correctly and the gpd reports correctly whether or not the server is running, I will defer this investigation to the next release.
