The exception cause is [still the same](https://github.com/openjdk/jdk/blob/73f93920b950b4ce5fa177db50010e95265d6a7f/src/java.base/share/classes/sun/security/ssl/NamedGroup.java#L780), we would throw the same exception if the named group were unavailable instead of being algorithm-constrained.

On the closer look, I think filtering named groups is better to be dealt with as a separate issue. Removing namedGroup changes and renaming the ticket.
