Re: Random DRDA Error on IBM J9 JVM Brandon L. Duncan Wed Apr 04 13:00:59 2012

Peter, definitely using the 10.8.2.2 jars. The scenario, which I'm in the
process of parsing down to share on JIRA is a single shell script called
from qsh to start the network server, run ij, and finally shutdown the
network server. The same classpath is shared through all three java calls.
