Ceki Gulcu commented on LBCORE-224:
-----------------------------------

I am able to reproduce the problem on Windows 7 with the following JDKs:

1) Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
2) Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)

On JDK 1.5.0_21-b01 (same OS and machine) I am unable to reproduce the IlelgalMonitorException. On Ubuntu (virtual machine running on same host as previously), I also unable to reproduce the problem. 

It looks like the problem is a JDK 1.6 issue when running on Windows. My next step is to write a test case which does not depend on zookeeper. I'll keep you posted.
