Optimization Unit testing and compilation on Eclipse #7
- Resolve OutOfMemory -> too created threads  because each DefaultEventManager instance is never shutdown
- Change ServerCase to abstract (exclude of test running in eclipse)
- correct CDOMany2OneNoRevTest failed -> primary key used for Artist is already existing in database
- Add in maven some build path directories generated sources (for eclipse)
