If you use the latest JBoss Tools 4.1 target platform, which now includes Kepler M6, you will discover that some of your tests may fail due to the fact that org.junit4 has been removed from Eclipse 4.3.0.M6. Please update your tests' plugins/features to depend on org.junit_4.11 instad of org.junit4_4.8. Similarly, if you depend on SWTBot 2.0.5, please update your dependency to SWTBot 2.1.
