Under the assumption that low arity methods greatly outnumber high arity ones, some cost here would be acceptable. But let's try to avoid it while keeping things simple. An option would be to split the code into a fast-path that has an unrolled loop dealing with N args, then a slow path that does more or less the old logic with an ArrayList which we fall back to as soon as we hit either an argument that is too long or we go past N. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20611#issuecomment-2294506811
