RFR: 8343378: Exceptions in javax/management DeadLockTest.java do not cause test failure

[Kevin Walls]

Test update: fail when it hits an Exception.

This test still references jmxmp and iiop, which are of course redundant, there are various tests that still do this.
I am working on http, so we may revisit these tests in future to change their list of protocols.

For now, I'd like to simply make this test fail if any of the protocols it tests have failures.
Fix a few typos while we are here.
