It might be safer to not change that behavior. I'm 99% sure the original intention was for the empty pattern to be rejected with IAE. It was an implementation but that it checked if the index is length rather than length-1. That was JDK 7 and changing is now without be behavior change. I can't imagine the impact would be significant but I agree it's not worth it and maybe we just drop the check as per the JBS issue and update the spec to document the long standing behavior. ------------- PR: https://git.openjdk.org/jdk/pull/9595
