      When the server.lock does not have the correct permission set and cannot be accessed in the artemis log it just seems to hang and does not report any error . Also nothing is obvious why it is hanging from the thread dump.

      However when I looked at the console/terminal output it reported the "FileNotFoundException".

      This exception should be logged to the log file as it is very difficult to spot if you miss the standard/error output and are only review the artemis log.
