using debug to get the exception detail as below:

and it should caused by MPING received a message, but the jchannel initialize doesn't done at this time. (TCPConnectionMap(ct) doesn't initialized in TCP). 

I guess this error should be harmless, but I think MPING should receive message after jchannel initialze done.
