NPE in Kaha

[drvillo <f....@gmail.com>]

Hi all

I'm not able to remove messages any more from a Kaha store, after a
recovery.
Below is the trace I get:



Exception in thread "Timer-1" java.lang.NullPointerException

        at java.util.TimerThread.run(Timer.java:462)



I'm running rev 490007, quite old I know but it seems that newer version are
incompatible 
with the existing store. Before upgrading I'd like to know about 4.2 status
(see the other post)

Thanks a lot

Francesco
