This doesn't exactly apply to your situation, but I had the same thing -- tests that would pass in Eclipse failed when the test goal from Maven was run.

It turned out to be a test earlier in my suite, in a different package. This took me a week to solve!

An earlier test was testing some Logback classes, and created a Logback context from a config file.

The later test was testing a subclass of Spring's SimpleRestTemplate, and somehow, the earlier Logback context was held, with DEBUG on. This caused extra calls to be made in RestTemplate to log HttpStatus, etc.

It's another thing to check if one ever gets into this situation. I fixed my problem by injecting some Mocks into my Logback test class, so that no real Logback contexts were created.
