When running jconsole connecting to pid 4336 on my laptop I noticed that heap memory usage goes up and down between 4k and 8k, even when no java programs are running. It also shows that 3105 classes are loaded, and, 30 live threads are running. I am running Win XP.

Do these consist of the Java Environment (JDK)? In what ways can jconsole help me monitor java applications for memory leaks and performance issues? Have you ever encountered a memory leak when working with Java?

Maybe its the JConsole itself?

While you can certainly use jconcole to do the monitoring, visualvm is a much more powerful tool.

I think this question is too difficult for "beginning". Moving thread.
