Windows 10. Latest IDEA. Same environment and tests, nothing special, but suddenly a crash... twice
hs_err_pid10888.log
hs_err_pid14376.log

I have changed JDK to Liberica 20.0.1 and instead of a crash I have received NullPointerException!

It looks like ConcurrentHashMap.values().iterator().next() CAN return null.
After I have added check for this possibility, no more NPE and crashes yet (on JDK 17 too)
