> I used IBM JDK 6, SR10 to individually run several unit tests, like  `mvn test -Dtest=org.apache.hadoop.hbase.mapreduce.TestHFileOutputFormat`,
then there are JVM crush issues(detail log is as following) existed. There may be programming
issues like passing a null or no-defined parameters into sun_misc_Unsafe_getLong__Ljava_lang_Object(),
and I looked into some class, it really calls Unsafe.getLong(), which still need to be fixed
by deeply debugging every unit test codes' passing values case by case.
