mine test command is:

test=jdk/test/java/net/MulticastSocket/Promiscuous.java
nproc=`nproc` ; dir="tmp-jtreg-"`basename $test .java` ; rm -rf $dir ; mkdir -p $dir ; time seq 1000 | xargs -i -n 1 -P `expr $nproc / 2` bash -c "jtreg -ea -esa -timeoutFactor:4 -v:fail,error,time,nopass -nr -w $dir/index-{} $test &> $dir/{}.log ; grep 'Test results: passed: 1' -L $dir/{}.log"
