We are using Sun 1.5 for the worker nodes/user machines with no problems so far,
we also install the jpackage based rpms since the standard RHEL java rpms (ibm,
jrockit,gcj) are all based on jpackage and they play nicely together. I had
problems at the past with both the ibm and jrocket VMs (not grid related) so
the default system VM is the sun one but I am going to try the ibm 1.5 one
some time soon.
