    Description

      We just saw exceptions like these:

      Exception in thread "B.DefaultRpcServer.handler=45,queue=0,port=60020" java.lang.NullPointerException
      	at org.apache.hadoop.hbase.ipc.RpcServer$Listener.getAddress(RpcServer.java:753)
      	at org.apache.hadoop.hbase.ipc.RpcServer.getListenerAddress(RpcServer.java:2157)
      	at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:146)
      	at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop(RpcExecutor.java:130)
      	at org.apache.hadoop.hbase.ipc.RpcExecutor$1.run(RpcExecutor.java:107)
      	at java.lang.Thread.run(Thread.java:745)
      

      Looks like RpcServer$Listener.getAddress should be synchronized (acceptChannel is set to null upon exiting the thread under in a synchronized block).

      Should be happening very rarely only.
