When trying to workout why a maven build is failing, I used these options to switch on JMX support inside Maven. Once Maven was running I connected jconsole to read the stats.

Log lines have their thread name:

MAVEN_OPTS=" -Dorg.slf4j.simpleLogger.showThreadName=true"

Port to listen on:

MAVEN_OPTS+=" -Dcom.sun.management.jmxremote.port=9010"

Allow remote connections:

MAVEN_OPTS+=" -Dcom.sun.management.jmxremote.local.only=false"

Switch off authentication:

MAVEN_OPTS+=" -Dcom.sun.management.jmxremote.authenticate=false"

Make sure app binds to the external interface:

MAVEN_OPTS+=" -Djava.rmi.server.hostname=vmware"

Make sure no security stuff gets in the way:

MAVEN_OPTS+=" -Djava.security.policy=all.policy"

Switch off SSL, so there is no complaining about certificates:

MAVEN_OPTS+=" -Dcom.sun.management.jmxremote.ssl=false"
