      • insert 10 text messages with a small body size (using the CORE protocol)
      • insert 1 text message with body size 80000 char. (char is stored in 2 bytes so it will trigger default large message size 100Kib)
      • invoke browse() operation from within jolokia
      • results in Nullpointer exception as above.
