Sure, that could be helpful. I don't think it should be a warning on the OS API though. Looking at the code a log message like that could be added to `CPUTimeThreadClosure::do_thread(...)`. To me it would be enough to have that on `log_info(cpu)` possibly even on debug-level. What do you think? ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/26621#discussion_r2278420082
