jdk/jfr/event/runtime/TestShutdownEvent.java failed in validateStackTrace()

This is likely a product bug (not a test bug), for the initial evaluation.
Frequency: fails about once a week in CI
Platform: only seen on Windows so far
Update: added a sighting on Linux.


The test uses Unsafe to write 0 into 0 address, thus causing Access Vialation, and the JFR recording dump.
Test verifies the recording, specifically the ShutdownEvent. Looks like the stack trace is incorrect, thus test asserts.
