Reason: "+e.getMessage()); return defaultValue; } } </pre> It doesn't print to standard output anything (neither argument message). I may press enter key many times, it add new line to screen, but the method doesn't return. It block forever and I have to kill it :-( It seems obvious, that I am not not first man who encountered this issue.
