Hi Chris, [Forwarding to architecture@]
We thought of having some meaningful names for the exceptions. So came up with this, which include the "Failed" part. I was looking into some references on exception thrown when sending messages, before coming up with these names. For example [1]. WDYT? Thanks, Kishanthan.
