> CASSANDRA-5664 simplified the decoding method of CredentialsMessage by using
> CBUtil.readStringMap (instead of duplicating the code). Unfortunately, that
> latter method turns his keys to uppercase (to provide some form of case
> insensitivity for keys), and in the case of CredentialsMessage this breaks
> PasswordAuthenticator that expect lowercased keys (besides, it's a bad idea
> to mess up with the case of the credentials map in general).
> Making CBUtil.readStringMap uppercase keys was probably a bad idea in the
> first place (as nothing in the method name imply this), so attaching patch
> that remove this (and uppercase keys specifically in StartupMessage where
> that was done on purpose).
