UIMA AS service not logging a msg about missing JMX property

UIMA AS service wrapper doesn't log a msg when it detects missing jmx monitor property. The service simply starts with no hint of misconfiguration. The jmx monitor is optional, but requires two parameters: the rate at which to collect stats and jmx port of the monitored service. The latter is specified via -Dcom.sun.management.jmxremote.port=xxx property. If omitted, UIMA AS service wrapper just proceeds as if the jmx monitor was not requested by a user. Modify code to log a message indicating that the jmx port is missing and exit the process.
