java.lang.IncompatibleClassChangeError: Implementing class
Gus
I seem to get this anytime I use PowerMock.create(Class)... I searched
the issues and this forum and didn't find anything about it. I
verified that @PrepareForTest was being picked up, because when I
tried to use EasyMock.create(Class) I got the Logging problem... If I
got rid of @PrepareForTest, the log4j problem went away, and then I
solved it with @PowerMockIgnore({"org.apache.log4j",
"org.apache.commons.logging"}), and put PowerMock.create() back in...
But I still get:

Never seen this before. If you upgrade to Javassist 3.11 do you still
get the same problem? If you do could you please attach an example
demonstrating the issue to our google group?

and just use this SomeObject...
public class SomeObject
{
private int foo;
public int getFoo()
{
return foo;
}
private void setFoo( int foo )
{
this.foo = foo;
}
public void recalc(int baz) {
setFoo(baz/2);
}

Which version of JUnit are you using? I am experiencing a similar
problem on our build server, but my tests run OK in Eclipse.
Currently, I am trying to figure out whether it was caused by the
older version of JUnit (version 4.4).
Thanks,
Ben

using powermock-easymock-1.3.5, Junit 4.4, easymock-2.5.2 and
easymockclassextension-2.5.2. The exception seems to be getting thrown
when I mock the parse method of android.net.Uri

into the same issue. I was running EasyMock 2.4 with PowerMock 1.2.5
and everything was working fine. However, to get the ability to use
EasyMock's new capture multiple values feature in 2.5.2, I upgraded
both EasyMock and Powermock (2.5.2 and 1.3.5 respectively). Since
then, all hell has broken loose. This is the main issue I'm running
into though so if you have any feedback, it's appreciated. Thanks in
advance!

Has there been any progress on this front since it was reported a few
weeks ago?

Thanks a lot for taking the time to reply.
Yes, the issue is now fixed — using the powermock + eazymock full
package (all dependencies included) solved the problem :-)

Hey Johan,
I am using PowerMockito.
Here is what I am doing:
@RunWith(PowerMockRunner.class)
@PrepareForTest(Foo.class)
public class PowerMockTest {
@Test
public void testSomething() throws Exception {
Bar bar = new Bar(null, null, null);
PowerMockito.mockStatic(Foo.class);
Mockito.when(Foo.someMethod(Mockito.anyString())).thenReturn("success");
String str = bar.someOtherMethod();
}
}
//Foo is my class which has a static method someMethod()
//Bar calls this static method from someOtherMethod()
I am getting the following error:
java.lang.IncompatibleClassChangeError: Class com.sun.jmx.mbeanserver.JmxMBeanServer does not implement the requested interface javax.management.MBeanServerConnection
...
...
...
I am using the following versions:
powermock-mockito-1.5
mockito-core-1.9.5
junit-4.7
objenesis-1.2
javassist-3.17.1
Help much appreciated!
Thanks
Pranay
