I found that there isn't " java.lang.management" in the IBM JDK 1.6
So pp-agent can't suppot  the  IBM JDK 1.6, is it right?

 @shenhongwei33 @chuanyi-fang 
Looks like your version of ibm java 6 does not have the method above.
We'll fix the startup error in the next version.

In the mean time, could you try it again with the jdk 6 downloaded from the ibm website?
Thanks. #3579  This issue/proposal has been automatically marked as stale because it hasn't had any recent activity. It will automatically be closed if no further activity occurs for 20days. If you think this should still be open, or the problem still persists, just pop a reply in the comments and one of the maintainers will (try!) to follow up. Thank you for your interest and contribution to the Pinpoint Community.
