How much memory does my java thread take?

Question

Is there a way to find out how much memory my java thread is taking in the VM?

For example, using stack trace dump, or some other means.

Thanks

Java threads use the heap as shared memory. Individual threads have their stack (the size of which you can set via the -Xss command line option, default is 512KB), but all other memory (the heap) does not belong to specific threads, and asking how much of it one specific thread uses simply does not make sense.
