Failed to transform class with name foo.TempTest Reason: 3

[GoogleCodeExporter]

I'm getting a "Failed to transform class with name foo.TempTest Reason: 3" 
error when mocking a static method. 

My test is this:

@RunWith(PowerMockRunner.class)  
@PrepareForTest({Utils2.class})  
public class TempTest {

    @Test
    public void say() {
    }
}

And Utils2 class:

public class Utils2 {
    public static String say(String s) {
        return s;
    }
}

The stack trace when exception is thrown is:

java.lang.IllegalStateException: Failed to transform class with name 
com.crossfence.service.TempTest. Reason: 3

I got the exception when adding this test to an existing project. However, it 
works fine if I create a new project with just these two classes. Therefore 
this could be an envrionement issue. 

I'm using these verions:
junit 4.8.2, easymock 3.0, powermock 1.4.10, and javassist 3.12.0.GA.

The operating system is Windows 7.

How do I troubleshoot this? Are there loggings I can turn on?

Let me know if you need more information.

Thanks!

Hi, 

Try upgraded to Javassist 3.15 GA and see if it works

Worked. Thanks! Actually Javassist 3.6 was used. 3.12 GA works as well.

It's important that you use the correct dependencies otherwise PowerMock won't 
work.
