Found the following threads showing up in a funny stated when attaching jvisualvm to the hung SMX instance (see attached file StackTraces.txt).

Thread Blueprint-Extender-2 seems to be cycling from active to blocking but does never finish its call to NamespaceHandlerRegistryImpl.getNamespaceHandlers().
The threads Blueprint-Extender-1 and -3 are blocked all the time waiting on the lock that Blueprint-Extender-2 owns.
