      Description

      I tried to check Monitor Cache Dump in HSDB, but it hangs and OOME occurred.

      How to reproduce:

        1. Run JShell
        2. Attach HSDB to JShell
           $ jhsdb hsdb --pid <PID>
        3. Select "Monitor Cache Dump" in "Tools" menu.

      ObjectSynchronizer$ObjectMonitorIterator switches monitor block list when index == 0 at next(). However next() switches blockAddr only.
      We should also switch "block".
