management-agent.jar is the java agent that is used with the attach API to start the JMX agent in a target VM. It's the approach used in JDK 6 to start JMX in a running VM and predates the "jcmd ManagementAgent.start" command added in 7uX.
JDK-8044135 added an API in the attach framework to start the JMX agent, and it is now time to remove management-agent.jar. webrev: http://cr.openjdk.java.net/~sla/8043939/webrev.00/ bug: https://bugs.openjdk.java.net/browse/JDK-8043939 Thanks, /Staffan
