java.lang.IllegalAccessError when using PowerMock 1.6.0 and Mockito 1.10.16 #533

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1. The following test class can reproduce the issue:

@RunWith(PowerMockRunner.class)
@PrepareForTest({StringBuilder.class})
public class BugTest {

    @Before
    public void setUp() throws Exception {
        mockStatic(StringBuilder.class);
    }

    @Test
    public void testSomething() throws Exception {

    }
}

What is the expected output? What do you see instead?

The test fails to run. Instead it breaks with the following stack trace:

What version of the product are you using? On what operating system?

PowerMock 1.6.0 with Mockito 1.10.16 using Java 1.7.0_72 on Ubuntu 14.04 64-bit

Same problem with PowerMock 1.6.1, Mockito 1.10.17, Java 1.8.0_40, OS X 10.10.2 
while trying to mock a class with the mock() method of PowerMock:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

import static org.mockito.Matchers.anyVararg;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.whenNew;

@RunWith(PowerMockRunner.class)
@PrepareForTest(App.class)
public class AppShould {

    @Test
    public void startWithArguments() throws Exception {
        final App appMock = mock(App.class);
        whenNew(App.class).withNoArguments().thenReturn(appMock);
        App.main(new String[]{"server", "config.yaml"});
        verify(appMock, times(1)).run(anyVararg());
    }
}

The exception thrown is:

java.lang.IllegalAccessError: tried to access class 
org.mockito.internal.creation.cglib.CGLIBHacker from class 
org.mockito.internal.creation.MethodInterceptorFilter

It seems to be fixed with PowerMock 1.6.2!
