It would be good to use a path unique for this test to avoid potential interferences. I would suggest registering the context under "/HttpResponseInputStreamInterruptTest/" instead of "/".

And use that when building the URI below as well.

This is important because the handler is using latches, and therefore can be invoked only once...
