We use a size of 256 so C2 can apply array bound check elimination as it knows the resulting value from `& 0xFF` is ensured to be in the range of `[0, 255]`, which is always valid for the array, so its generated code will drop the bound check. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23337#issuecomment-2621982177
