Was running a scripts which continually started/stopped replicated leveldb instance nodes that looked like:| while true ; do|
| ./bin/activemq console & |
| pid=$! |
| sleep 30 |
| echo Killing $pid |
| kill -9 $pid |
| sleep 5 |
| done |
Found that the following NullPointerExceptions were logged during the execution of the test:| Exception in thread "hawtdispatch-DEFAULT-1" java.lang.NullPointerException|
