I noticed the grammar we have for switch labels does not match the reference grammar at https://docs.oracle.com/javase/specs/jls/se25/html/jls-14.html#jls-SwitchLabel. For instance our grammar allows things like
case null, null, null, defaultor specifying multiple guard clauses when at most one is permitted.Describe the PR
