Fix OldJarFileTest: move initialization to setUp()

CTS test execution appears to have started deleting the temp dir
created at construction time before the test is run in _some_
circumstances. The test was doing work at construction, which
is incorrect.

Also updated Support_Resources to throw exceptions not log
them.
