RFR: 8282036: [Test]: Update java/util/zip/ZipFile/DeleteTempJar.java to stop HttpServer cleanly in case of exceptions

[Thejasvi Voniadka]

This is a simple change to add some protective code to java/util/zip/ZipFile/DeleteTempJar.java so that the clean-up is more complete in the event of encountering an any exceptions while running. In the present state, the server.stop() does not get executed in case of encountering a failure. As a result, the test may get hung until a timeout. This fix should address the scenario.

The test passes on all supported platforms post fix.
