IllegalAccessError when running Infinispan servers within AS7

Apparently package protected access does not work between classloaders, so Infinispan servers are not currently usable in EDG!

17:13:35,468 WARNING [org.jboss.netty.channel.DefaultChannelPipeline] (HotRodServerWorker-2-1) An exception was thrown by a user handler while handling an exception event ([id: 0x02916ab8, /127.0.0.1:58211 => /127.0.0.1:11222] EXCEPTION: java.lang.IllegalAccessError: tried to access class org.jboss.netty.handler.codec.replay.UnsafeDynamicChannelBuffer from class org.jboss.netty.handler.codec.replay.CustomReplayingDecoder): java.lang.NullPointerException

Forget about the NPE, the root cause is the IllegalAccessError.

There're different avenues to get around the issue... I'm starting a dev thread on this.
