I'd vote for a change to catch the exception and
ignore the message. After all, free implementations
may (have) come up with more understandable,
localized, superior messages to those provided by
Sun's implementation. It would be counterproductive to
force them to change them  to Sun's version.

I think the essential question here is: can having
different hash methods bite you in some way? Beside
obvious hashing performance considerations, I doubt
it.
