fixed stopping IrTrans: close InSocket
fixed stopping OSKA: changed order of commands:
1) send close to Oska
2) close socket
3) kill process
added some better logging statements.
added safety check in bufferData to not synchronize with null object
pool size is not configurable any more --> changed to newCachedThreadPool strategy again to not risk busy threads that lead to a deadlock
Do not automatically execute timeouted task in fallbackPool but simply throw TimeoutException
In case of exception when trying to start model, the model is stopped again and afterwards MODEL_EXECUTOR is switched to fallbackPool
