tools for debugging.

Ive been trying to debug the iso9669 device to find out why it doesnt show any files for one of my cd's.

it occurs to me that its really hard to see whats going on, just because of the number of classes and interactions within them.

One software tool i use has a method trace feature that causes the VM to output the method name whenever it enters or exits a method.

it would be a useful "coarse" tool to see which classes are involved with a given action.
