Surefire plugin error message does not indicate the source of the error.

I have been getting test failures. But maven provides no hints as to the root cause of the failures. I have tried using the -X and the -e options, but all I get is this. I don't konw if this is a maven issue or a surefire plugin issue. But, the exceptions should have enough data on what tests failed. This has made it impossible for us to track down the issue. This doesn't happend on developer machines. It only happens on teh build machine that we are trying to setup.

The command we ran was:

mvn -e clean test
