Patch: FYI: test for chaining oddity

[Tom Tromey]

I'm checking this in.

I wrote this test to check the behavior of exception chaining in an
odd situation.  I think this behavior is pretty broken, but we do
agree with the JDK here, so I'm checking it in.  Also I figured that
if the JDK is ever fixed this will let us notice.
