When running ubsan-enabled binaries on macOS aarch64, in test
javax/management/MBeanServer/OldMBeanServerTest.java
the following division by zero is shown :
src/jdk.management/macosx/native/libmanagement_ext/UnixOperatingSystem.c:67:40: runtime error: division by zero
UndefinedBehaviorSanitizer:DEADLYSIGNAL
UndefinedBehaviorSanitizer: nested bug in the same thread, aborting.
This seems to come from the division by a total_delta (of ticks) == 0 :
jlong used_delta = used - last_used;
jlong total_delta = total - last_total;
jdouble cpu = (jdouble) used_delta / total_delta;
