JRockit Mission Control Console Cannot be Started

Today I had an issue that the JRockit mission control cannot be started. The problem is when trying to start mission control from windows programs, the mission control splash flashed and disappeared right away. Something is blocking the process to be started properly.

The key to this issue is to start JRockit mission control using debug command-line. From windows:

%JROCKIT_HOME%\bin\jrmc -consoleLog 2>1& | more

Here was the output I got:

By checking the debug info, I can see that the console setting config xml file -- "C:\Documents and Settings\jzheng\.jrmc\4.0.1\rjmx.4.0.1.xml" is the trouble spot. After I deleted the file, the console was able to be started properly.
