--------------------------------------------------------------

[~cshannon] Before this change, the broker closes the connection on max message 
failure without delivering any packets to the client. The is represented on the 
client-side as an IOException and no indication of why. When failover is 
configured, it would infinitely retry a message that is too large.

With this change, a well formed exception is returned to the client. The client 
does not *need* to close the connection, they can if they choose-- or the "too 
large" message could be logged and the next one goes through on the same 
connection without a problem.

>          Components: JMS client
>            Reporter: Matt Pavlovich
>            Assignee: Jean-Baptiste Onofré
>            Priority: Major
>             Fix For: 5.17.0, 5.16.4

> Currently, clients get an inconclusive exception when a message that is too 
> large is sent. We should send a well-formed message, and then close.
> Options: 
> 1. Change the current IOException to something else to fall within existing 
> exception flow
> 2. Update current exception handling to send ExceptionResponse w/ the max 
> message size message to the client before closing
