             Summary: CLONE - "VerifyError: Inconsistent stackmap frames" from PowerMock (using Javassist 3.18.1)
                 Key: JASSIST-215
                 URL: https://issues.jboss.org/browse/JASSIST-215
             Project: Javassist
          Issue Type: Bug
    Affects Versions: 3.18.0-GA
         Environment: jdk1.7.0_21, Win8amd64
            Reporter: Laurent GARCIA
            Assignee: Shigeru Chiba
             Fix For: 3.18.1-GA, 3.19.0-GA


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();
		}
	}
}
{code}

And here is my error:

{code}
