    This looks like a JConsole problem. I guess be sure yoiu are running the one that comes with the latest Oracle Java JDK.

    Default yep - the latest as far as i know

    this is the jconsole info:

    JConsole version: 1.6.0_22-b04
    Java VM version: Java HotSpot(TM) Client VM, 17.1-b03

    actually - i don't need it since i found a better way for what i need the CHECK_JMX querying script but i thought that if this is a bug - better notify about it to improve the wowza product
