P4
The JVM truncates option values that are greater than the size of the specified option, instead of reporting the values as illegal.
For example, for int option -XX:DeoptimizeObjectsALotThreadCountAll=10123345670 (0x25B65FF06), the JVM assigns the value 1533411078 (0x5B65FF06) to DeoptimizeObjectsALotThreadCountAll.
Similarly, for 64 bit options:
> java -XX:+PrintFlagsFinal -Xint -XX:MaxJNILocalCapacity=12345123451234512345 2>&1 | grep MaxJNILocalCapacity
> intx MaxJNILocalCapacity = -6101620622475039271
