AI 147896: Some more fixes for tests that failed in

  the CTS, but worked fine in run-core-tests:
  - One cert test needs isolation, because
  it destroys the security provider.
  - The Thread.sleep() tests were too flaky.
  - Tests that tried to open a temporary DEX
  file failed in the CTS because we do not
  have access to the system DEX cache. We
  are now simply creating our own.
  The Java plan in the CTS should now pass
  fully. Yippie!
