If given a tuple, isinstance and issubclass call themselves with each item of the tuple. If given a nested tuple, they can recurse into themselves many times. test_isinstance checks that a deeply nested tuple doesn't cause a stack blowup. Jython's isinstance and issubclass don't check how many times they've recursed so this causes a StackOverflow. This test is commented out for now as explained in http://wiki.python.org/jython/JythonDeveloperGuide/VersionTransitionTestExclusions

Since python sets a default recursion limit of 1000 for isinstance and issubclass functions in ceval.c the same logic can be implemented in jython. On reaching the recursion limit an OverflowError can be raised

Jython has a recursionlimit variable just like CPython: PySystemState.recursionlimit. It's just a matter of actually implementing what you recommended.
