RFR: 8357172: Extend try block in nsk/jdi tests to capture exceptions thrown by Debuggee.classByName()

[Chris Plummer]

Extend try block to cover debuggee.classByname() call. I would suggest disabling whitespace diffs when doing the review. It makes code movement and deletions more obvious.

There are a number of places where I removed a try/catch of InterruptedException around a Thread.sleep. This will now be handled by the outer try which was moved to before this try/catch.

Tested nsk/jdi test locally. Will do more thorough ci testing.
