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. */ public class LoadHandlerInTry { public static void main(String[] args) throws Exception { System.out.println("Regression test for bug 8075118"); try { Class newClass = Class.forName("HandlerInTry"); } catch (Exception e) { System.out.println("Failed: Exception was thrown: " + e.toString()); throw e; } try { Class newClass = Class.forName("IsolatedHandlerInTry"); throw new RuntimeException( "Failed to throw VerifyError for IsolatedHandlerInTry"); } catch (java.lang.VerifyError e) { System.out.println("Passed: VerifyError exception was thrown"); } } }
