mkdir bin-dragonwell8;tar -xf ${BINARY_URL##*/} -C bin-dragonwell8

部署jtreg工具：

部署用例repo
git clone -b $JDK_BRANCH $JDK_REPO jdk-repo

执行以下命令：
jtreg  -nr -v:fail,error -w tmp -Xmixed jdk-repo-dragonwell8/jdk/test/java/lang/ThreadGroup/NullThreadName.java

【测试分析】
x64，aarch64的release，fastdebug都有问题，失败率6/50，复现命令
