Right, if the thread invokes a Java native method then it may or may not invoke a system call, it doesn't matter, the ThreadInfo::isInNative method is just reporting a bit of thread state to say that it is in a native method. Same thing when calling a native function with the FFM API, the native function may be a syscall, or the native code may invoke a syscall, it doesn't matter to ThreadInfo::isInNative as it just returns a bit of thread state. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/16791#discussion_r1407275856
