Tests passing when run by ant but fail when run by maven?

Question

Does anyone have any ideas why a test would pass when run with ant, but fail when run with maven?

I'm running my tests on windows and apparently there are some issues with surefire and windows? I've tried changing useSystemClassLoader=False and useManifestOnlyJar=true, but haven't been able to get them to work. The stack is below for the error I am getting when running the test with maven.

One thing I noticed is that there are $Proxy.someMethod calls in the stack, I have no idea where they are coming from.

Thanks for any help.

Setting forkMode=never in the sure fire configuration resolved the issue. I'm not sure of the reasoning, but without this option maven wasn't running pre-test code that ant was.
