Renaming throw type and exception parameter err msg to incompatible

[Ao-senXiong]

I will do the two renaming first as they are the most related to our changes in #436.

Did you look through the manual whether this needs changing somewhere?
This definitely needs a changelog entry.
Can we support both suppression keys for a transition period?

I have looked at the manual and there is no similar message key used in the manual.

This definitely needs a changelog entry

Already add a changelog entry.

Can we support both suppression keys for a transition period?

I have added back to old keys for this transition period.

I have added back to old keys for this transition period.

You left the old keys in messages.properties, where nobody uses them. You can remove them there.

Can we allow existing @SuppressWarnings that use the old keys to continue to work? Otherwise, we're breaking everyone that currently suppresses these warnings and force them to change the keys.
