[kaffe] Kaffe and RXTX on XSCALE

[asutosh gopinath]

hi,
I am trying to run SimpleWrite. I get following error:

SimpleWrite: Error setting event notification: java.lang.NullPointerException
java.lang.NullPointerException
   at gnu.io.RXTXPort$MonitorThread.run (RXTXPort.java:1530)   


verbosejit says java/lang/ThreadGroup.uncaughtException
I'm pasting a portion of JIT below:
