Java Performance Analyser

Occasionally I get "Out Of Memory" error in my Apache Tomcat and with out thinking too much I will just bounce the server to solve the problem. I was searching for the same in Google and it took me to a blog post http://opcodesolutions.com/tech/solve-java-lang-outofmemoryerror-java-heap-space/ in which I found an interesting tool Visual VM.
My goal is not to re-produce every detail about this tool, Name says it all.
http://visualvm.java.net/
I just downloaded it and got up and running in seconds. I have not yet started playing with the tool, but I believe this will solve some of my Java Memory issues.
You can go through the screen cast of this tool from this page.
