> In Java 7 the reflection-implementation was changed so that tests in the same test-class
are not necessarily executed in the same order they are written. Changing the order of the
tests and using JDK-6 makes this issue 100% reproducible for me.
> This may cause the Tests in MainStartTest to be executed in reverse order, which will
cause "testAutoStart" to fail because "testStopWithTimeout" did not clean up correctly.
