Debugger that watches jvm running a BlackBerry application on device simulator

I need a debugger that watches jvm running a BlackBerry application on device simulator (the same way as OllyDbg is used to deb开发者_Python百科ug Windows applications.) Any recommends?

The BlackBerry JDE and Eclipse plugins both have debugging tools built in to them. Is there something specific you're looking for that these tools don't provide? They're quite comprehensive - code stepping, memory monitoring, process and thread dumps, etc.
