[Opensymphony-oscache] Initialization Error w/ jgroups 2.2.8

I'm currently at a loss when I try to go from javagroups 2.2.7 to
javagroups 2.2.8 with oscache 2.2.1.  I get this exception:

===cut===

===end cut===

The class org.jgroups.Address class is indeed in the javagroups jar file
with all the other jgroups classes.  I get some jgroups messages after
this error too (binding to interfaces etc).  Also, a bunch of these:
===cut===
 INFO
com.opensymphony.oscache.plugins.clustersupport.JavaGroupsBroadcastingListener
- A new member at address '192.168.1.27:52770' has joined the cluster
===end cut===

So I'm very curios why the exception during initialization.  Any
thoughts?  I'm not sure this is an OSCache bug/issue but that is where
things are breaking.
