<br>
A Hot Rod protocol change might be required as a result of [1].<br>
<br>
In essence, the Hot Rod protocol does not specify how remote exec calls that return null should respond back to the client [2].<br>
<br>
Returning an empty byte[] won't cut it since returning an empty String would be represented that way, and that's different to null.<br>
<br>
I don't know how this could be handled without modifying the protocol, any ideas?<br>
<br>
If modifying the protocol, adding a new status code would be a way to handle it.<br>
<br>
Thoughts?<br>
