I have not tried this myself. However, I think there are some limitations
in JDI/JDWP to be aware of. For example, when a user steps, a step request
is created and then the thread that is being stepped is resumed. There is
a notification (event) when the step completes, but there is no event when
the step starts. Similarly, when a thread is resumed from a breakpoint
there is no resume event. Thus, you will need to do something special to
synch all clients for these types of operations.
