Running following command(run TestGCOld hotspot jtreg test) cause JVM exit with SIGFPE signal:
java -XX:+UseConcMarkSweepGC -XX:CMSScheduleRemarkSamplingRatio=9223372036854775808 TestGCOld 10 10 10 10 10000

32 bit JVM also affected:
java -XX:+UseConcMarkSweepGC -XX:CMSOldPLABNumRefills=2147483648 TestGCOld 10 10 10 10 10000

The problem in overflow in CMSCollector::preclean() function:
void CMSCollector::preclean() {
...
    if (used < (capacity/(CMSScheduleRemarkSamplingRatio * 100)
                * CMSScheduleRemarkEdenPenetration)) {
...
}

CMSScheduleRemarkSamplingRatio have 'max_uintx' max range and 'CMSScheduleRemarkSamplingRatio * 100' can results in 0 due to the overflow and this can cause division by zero.
