Every time I try to handle (catch etc) an exception inside produceState it throws another exception at a higher level and crashes the application (I posted that exception inside the thread). Am I doing something wrong here?

ok solved it, the reason is completely unrelated and was another exception inside produceState, it is just weird that it didn't appear at all in the top level exception that was printed
