 /*
  * This test has two cases:
  *
  * 1. class HandlerInTry:  Class HandlerInTry contains a TRY block in a
  *    constructor whose handler is inside the same TRY block.  The last
  *    few bytecodes and exception table look like this:
  *
  *         ...
  *      87: athrow
  *      88: astore        4
  *      90: invokestatic  #9
  *      93: aload         4
  *      95: athrow
  *      96: return
  *    Exception table:
  *       from    to  target type
  *          36    46    53   Class java/lang/Throwable
  *          36    46    88   any
  *          53    90    88   any
  *
  * Note that the target for the third handler in the Exception table is
  * inside its TRY block.
  * Without the fix for bug JDK-8075118, this test will time out.
  *
  *
  * 2. class IsolatedHandlerInTry: Class IsolatedHandlerInTry also contains
  *    a TRY block in a constructoer whose handler is inside its TRY block.
  *    But the handler is only reachable if an exception is thrown.  The
  *    handler's bytecodes will not get parsed as part of parsing the TRY
  *    block.  They will only get parsed as a handler for the TRY block.
  *    Since the isolated handler does a 'return', a VerifyError exception
  *    should get thrown.
