复现命令：

test=jdk/test/java/lang/ClassLoader/deadlock/GetResource.java
nproc=`nproc` ; dir="tmp-jtreg-"`basename $test .java` ; rm -rf $dir ; mkdir -p $dir ; time seq 500 | xargs -i -n 1 -P $nproc bash -c "jtreg -ea -esa -XX:-UseCompressedOops -timeoutFactor:4 -v:fail,error,time,nopass -nr -w $dir/index-{} $test &> $dir/{}.log ; grep 'Test results: passed: 1' -L $dir/{}.log"
