* 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.
