Could you please join our mailing-list (go to
http://groups.google.com/group/powermock) and post questions there instead? 
Then I
would have discovered this much faster. 

Anyway I don't quite understand what you mean by "try to mock a static class 
with a
private interface". Are you saying that you're trying to mock an inner class 
that is
static that implements some interface?

Please respond on the mailing list instead of here.

The reason was that inner classes/interface didn't work well with PowerMock. It 
has
been improved in trunk and the above use case should now work.
