What about the case where there is a provider that supports the algorithm, but does not support the parameters? I thought we were going to iterate over the providers and try to instantiate each one with the supplied parameters. In that case `NoSuchAlgorithmException` is not appropriate.

@seanjmullan, @wangweij, @valeriepeng: See updates in https://github.com/openjdk/jdk/pull/20301/commits/1edc431cc85586171028daee1254a038fc315c83

This should represent the latest consensus.
