Misleading message logged when RuntimeException thrown within a call-back: "Rejecting message: ..."

This is in relation to QFJ-793.

When both settings RejectMessageOnUnhandledException and DisconnectOnError are set to Y and a RuntimeException is thrown within a call-back, QuickFIX/J will write to the log output messages like below:

<20140612-16:25:06, FIX.4.4:SENDER->TARGET, error> (Rejecting message: java.lang.RuntimeException: ... (with more details and the message)

2014-06-12 18:25:06 quickfix.Session disconnect

INFO: [FIX.4.4:SENDER->TARGET] Disconnecting: Auto disconnect

This is misleading because nothing is actually rejected (no reject message is sent back to the sender). The session is simply disconnected. I believe a slightly different wording should be used for this scenario, e.g "Failed to process message" instead of "Rejecting message".
