[jboss-jira] [JBoss JIRA] (JASSIST-205) "VerifyError: Inconsistent stackmap frames" from PowerMock (using Javassist 3.18)

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/JASSIST-205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796103#comment-12796103 ] 

Scott Marlow commented on JASSIST-205:
--------------------------------------

In PowerMockTestLatest.javap, we can see that a long is stored in local variable #4 (which should take slot #5 up also) but we can see that a reference is stored in local variable slot #5.

> Apologies if this is a duplicate of JASSIST-204. I didn't delve into the actual Javassist APIs used, I'm simply seeing an error in my PowerMock usage. Fortunately, this ticket provides a very simple test case for reproducibility.
> I was prompted to open a Javassist ticket by the following PowerMock ticket: https://code.google.com/p/powermock/issues/detail?id=355
> I'm attaching a very simple maven project with a unit test to demonstrate the problem.
> Here are the guts of the failing unit test:
> {code}
> @RunWith(PowerMockRunner.class)
> @PrepareForTest( {MyClassUnderTest.class} )
> public class PowerMockTest {
> 	/**************************************************************************
> 	 * Demonstrates an "Inconsistent stackmap frames" exception that results
> 	 * from PowerMock 1.5 and JDK 7.
> 	 *************************************************************************/
> 	@Test
> 	public void testWaitForExitMockMonitors() throws InterruptedException {
> 		resetAll();
> 		
> 		Object mockMonitor = createStrictMock(Object.class);
> 		MyClassUnderTest myClass = new MyClassUnderTest(mockMonitor);
> 		
> 		mockMonitor.wait(0);
> 		mockMonitor.notifyAll();
> 		
> 		replayAll();
> 		
> 		myClass	.run();
> 		
> 		verifyAll();
> 	}

> 	public static class MyClassUnderTest {
> 		private Object m_monitor;
> 		
> 		public MyClassUnderTest(Object monitor) {
> 			m_monitor = monitor;
> 		}
> 		
> 		public void run() throws InterruptedException {
> 			m_monitor.wait(0);
> 			m_monitor.notifyAll();
> 		}
