[jdk15u-dev] RFR: 8264752: SIGFPE crash with option FlightRecorderOptions:threadbuffersize=30M

Fri Oct 1 14:23:06 UTC 2021

I'd like to backport this fix to 15u for parity with 11u.
The patch applies almost cleanly except for copyright years. Additionally the added test TestBadOptionValues.java was modified to pass successfully.
Tested with jdk/jfr tests, new test fails without the patch, passes with it.
Follow-up fix JDK-8266206 is planned to be backported as well.
