Support PowerMock to run Android JUNIT tests

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to mock any Android final class

What is the expected output? What do you see instead?
Expect the class to get mocked.

What version of the product are you using? On what operating system?
1.6.1 on Win7 64 bit and running against Android 4.0 (API 16)

Please provide any additional information below.
I get the below stack trace. Apparently PowerMock uses javaassist to modify 
byte codes, however since Android uses DEX code, can PowerMock be modified to 
work with dexmaker-1.0.jar and dexmaker-mockito-1.0.jar similar to how Mockito 
does it ?

I think this might be similar, but I'm getting the below exception : 
java.lang.VerifyError: org/mockito/cglib/core/ReflectUtils

which occurs with a failure to setup: dexmaker-1.0.jar and 
dexmaker-mockito-1.0.jar
However I HAVE set those up properly, because my exissting mockito tests work 
fine. Power mock seems to be ignoring them.

I'm having the exact same issue. 

My tests using Mockito are running fine, but when I try to do a 
PowerMockito.spy I get an exception:
java.lang.VerifyError: org/mockito/cglib/core/ReflectUtils

Has anyone been able to fix this?
