Failed to transform class with name com.ibm.ecm.extension.PluginServiceCallbacks. Reason: com.ibm.mm.sdk.server.DKDatastoreICM #526

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Preparing a class @PrepareForTest(PluginServiceCallbacks.class)

What is the expected output? What do you see instead?
Expect it to prepare without exception. Instead fail with 
java.lang.IllegalStateException: Failed to transform class with name...
I tried with a PowerMock.mock and prepare the class since I has issue with 
Mockito, hoping it could work :)

What version of the product are you using? On what operating system?
powermockito 1.5.6 - Mockito 1.9.5 - Window 7 - JDK IBM 32bits

Please provide any additional information below.
This is a simple class, so I also tried with @Mock from Mockito without 
preparing the class, I know it doesn't really concern you but I thought it 
could help though. When mocking with Mockito, I get a ClassNotFoundException 
(see stack below. It makes sense because this is a plug-in running in a J2EE 
environment with some other dependencies provided. However for the test I just 
want to mock the class for one method so I though the dependency wouldn't be a 
problem for a mock.

Maybe I can't mock such a class or did something wrong? Thanks a lot, PowerMock 
helps us a lot!

Hi again,

actually this is not related to Mockito or PowerMock, I describe the problem 
here and gave a work around in the Mockito forum if it can help someone:

https://github.com/mockito/mockito/issues/127

This issue can be close :)
