Goran Pugar commented on AMQ-2606:
----------------------------------

Same scenario with disconnecting of NC happened after 
NegativeArraySizeException. Mine message loss happened also.

Here is stack trace:

> Problem is basically a copy of AMQ-2605, but caused by different exception on 
> TcpTransport.
> In setup with 2 brokers connected with ConduitBridge, we have a problem with 
> network connector which is every couple of days disconnected because of 
> ClassCastException on TcpTransport on other node.
> Network connector reconnects after some time (cca 1 min) by inactivity 
> checker, but we have some minor message loss since we use syncSend=false on 
> queues.
