I think the evaluation is not correct (lack of synchronization is an issue too).
main thread also writes the value and I think this is the problem here.
Look at line 148 - it resets `counter1` instead of `counter2` and this happens after the test sends `COMMAND_TEST1`. So if listener thread already handled caught exception, we get the failure.
