Stack overflow of the operand stack can't happen because the
virtual machine is required to run with a bounded stack. This
is verified by the byte-code verifier.
Execution stack overflow is possible if you cause unbounded
recursion. Stack frames are heap allocated (in blocks). An
overflow occurs when you run out of heap space, or when you
reach a user definable limit. I believe this limit is checked
on each method invokation.
Have fun,
