Andre Dietisheim commented on JBIDE-25915:
------------------------------------------
Having an NPE dumped in the log is something that we have to avoid.
Looking at the stack traces it's obvious that this is a bug in project-examples, it just happens that this is caused in the context of an openshift usecase.
