Debugging Java Thread CPU usage

In case you want to quickly find out which of your Java threads is the culprit in a JVM's high CPU usage, this tool is truly helpful.

Simply download topthreads.jar from http://lsd.luminis.nl/top-threads-plugin-for-jconsole/
and run your jconsole like this:

     jconsole -pluginpath topthreads.jar

Similar to 'jtop', just a little better.
