IllegalStateException (due to ArrayIndexOutOfBoundsException) when running PowerMock test

[toddrun]

I'm trying to run a test against a class that is stuck using a bunch
of statics and I've had success with powermock before - but not this
time. I'm pretty sure there's some dependency that's messed up, but I
don't even know where to start looking for a solution. Any help would
be appreciated!

The following is a dumbed down class and test, just to show that there
isn't anything out of the ordinary in my code:


public class DoTheThing {
private static final Logger logger =
LogManager.getLogger(DoTheThing.class);

public String doIt() {
logger.info("Fooing");
return Globals.getJiveProperty("foo", "bar");
}
}


@RunWith(PowerMockRunner.class)
@PrepareForTest({Appender.class} )
@SuppressStaticInitializationFor("com.doit.DoTheThing")
public class DoTheThingTest {

private DoTheThing thing;

@Mock private Logger mockLogger;

@Before
public void setup() {
thing = new DoTheThing();
Whitebox.setInternalState(DoTheThing.class, mockLogger);
PowerMockito.mockStatic(Globals.class);
}

@Test
public void doTest() {
when(Globals.getProperty("foo", "bar")).thenReturn("blah");

Assert.assertEquals("blah", thing.doIt());

PowerMockito.verifyStatic();
Globals.getProperty("foo", "bar");
verify(mockLogger).info("Fooing");
}

}

This results in:
java.lang.IllegalStateException: Failed to transform class with name
com.doit.DoTheThingTest. Reason: 3

Any help would be greatly appreciated! Happy to provide any additional
info to get this resolved (I can't imagine not being able to use
powermock - working with existing code will be unbearable - or at
least untestable - until I get this fixed).

Hi, 

It looks like problem with the byte-code manipulation. If you're lucky it could solve itself with the latest version of PowerMock (1.4.7) which uses a newer version of Javassist. So my first suggestion is that you should try upgrading and see how it goes.

It was indeed a problem with Javassist, but it was due to another
dependency pulling in an older version. I had suspected this and tried
to put an exclusion in, but until a colleague pointed out that I had
the wrong groupId, the old version of javassist keep trumping the one
provided by powermock.

Thanks for the help!

Thanks toddrun if it wasn't you I would spend some more hours figuring this out! Because only groupId was different javassist (old) and org.javassist (new).
