      Description

      After apply the patch of HBASE-5611, and tested on a 32-bit machine. This problem was triggered.
      Before this patch, TestHeapSize is passed by pure coincidence in 94.

        public static final long FIXED_OVERHEAD = ClassSize.align(
            ClassSize.OBJECT +
            ClassSize.ARRAY +
            30  * ClassSize.REFERENCE + Bytes.SIZEOF_INT +
            (6 * Bytes.SIZEOF_LONG) +
            Bytes.SIZEOF_BOOLEAN);
      

      Actually, there are 31 REFERENCEs and 5 LONGs in HRegion.
