ActiveMQ: Failed to start jmx connector

this question is originally posted here: http://www.nabble.com/Failed-to-start-jmx-connector-tf3920420s2354.html

I had installed ActiveMQ 4.1 on server with Windows Server 2003 Standard Edition, JDK 1.4.2 update 12. ActiveMQ can start and running, however, it failed  to start JMX.

Below is the logs:
