背景是 Jenkins 2.354 升级到 Jenkins 2.381 之后，jenkins启动就挂，看docker的启动记录，是exit(1)。
看报错信息是 Running with Java 8 from /usr/local/openjdk-8/jre,which is older than the minimum requeired version (Java 11).

请教了之前处理过这个问题的同事，最后他是这样解决的：

/home/docker/overlay2/XXXEEEE/diff/usr/local/bin# diff jenkins.sh jenkins.sh.bak

37c37
< exec /usr/local/jdk-11.0.2/bin/java -Duser.home="$JENKINS_HOME" "${java_opts_array[@]}" -jar ${JENKINS_WAR} "${jenkins_opts_array[@]}" "$@"
---
> exec java -Duser.home="$JENKINS_HOME" "${java_opts_array[@]}" -jar ${JENKINS_WAR} "${jenkins_opts_array[@]}" "$@"
