部署用例repo
git clone -b $JDK_BRANCH $JDK_REPO jdk-repo-dragonwell8

执行以下命令：
cd bin-dragonwell8/dragonwell-8.20.21/ && export JAVA_HOME=$PWD ; export PATH=$JAVA_HOME/bin:$PATH ; export TEST_JDK_HOME=$JAVA_HOME && cd -
cd jtreg ;export JT_HOME=$PWD ; export PATH=$PWD/bin:$PATH;cd -

【测试分析】
-Xmixed选项同样问题，x64和aarch64都有问题 ，失败率3/100，复现命令
