> If you start the GossipRouter without concurrent.jar on the classpath, a NoClassDefFoundError exception will occur.  However this information is hidden by GossipRouter error handing and the user is presented with the cryptic message:  "failed reading the magic number mapping file."
> I think there are severl ways to improve this situation.
> 1)  Update the GossipRouter example in the JGroups documentation to show what jars need to be on the classpath.
> 2)  Modify the GossipRouter or ClassConfigurator to reveal the underlying problem.
> Note that this error occurs when you start the GossipRouter per the doc without adding concurrent.jar to the classpath.
