The JavaMonitorsInStackTrace is internal option however we should not get SIGSEV here.

Here is the example:
-->java -client -XX:-JavaMonitorsInStackTrace
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0xfe77464c, pid=12876, tid=7

# Problematic frame:

#
# An error report file with more information is saved as:
