Is there some kind of weird "magic" happening here? @dholmes-ora Indeed it's a compiler magic, albeit not really weird. While the method execution only receives the evaluated value of `expr`, the method compilation has the expression in its original form. As a result, it can determine the result based on this information. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/17527#discussion_r1464415357
