[jboss-user] [Clustering/JBoss] - RoundRobin, new cluster member & SFSB == NPE

[pmadzik]

Hello,

I know that using RoundRobin policy for SFSB is not best idea, but nevertheless i don't expect behavior described below.

When new member joins to cluster, client crashes with NPE exception:

Is it bug in jboss?
I use 4.0.5.GA-ejb3 version. I didn't change anything in default configuration.
