I've tried

rm -rf ~/.m2/repository/org/jboss/remoting/
rm -rf ~/.m2/repository/org/jboss/ejb3/

and did a clean build (including clobbering thirdparty). 

Still seeing the error.

Disassembling LRUCachePolicy, I can see the 
protected field m_map

$ javap -c -classpath jboss-common-core.jar
org.jboss.util.LRUCachePolicy
Compiled from "LRUCachePolicy.java"
public class org.jboss.util.LRUCachePolicy extends java.lang.Object
implements org.jboss.util.CachePolicy{
protected java.util.Map m_map;

Disassembing LRUPool, it is expecting a HashMap not a Map
so this has obviously changed at some point.

$ javap -c -classpath jboss-remoting.jar
org.jboss.remoting.transport.socket.LRUPool
Compiled from "LRUPool.java"
public class org.jboss.remoting.transport.socket.LRUPool extends
org.jboss.util.LRUCachePolicy{

...

public java.util.Set getContents();
  Code:
   0:   aload_0
   1:   getfield        #12; //Field m_map:Ljava/util/HashMap;
   4:   invokevirtual   #13; //Method
java/util/HashMap.keySet:()Ljava/util/Set;
   7:   areturn

So JBoss Remoting needs recompiling over the latest
jboss-common-core

I don't know whether this fixes the other problems?
