在ubuntu18.04中安装OpenJDK OpenJ9后，我发现缺少可执行文件
提问于 2019-06-20 11:58:33
我最近在我的Ubuntu18.04机器上从https://launchpad.net/~rpardini/+archive/ubuntu/adoptopenjdk安装了OpenJ9 jvm，并在我的终端上收到了这样的通知：
** Missing executable /usr/lib/jvm/adoptopenjdk-11-jdk-
openj9/bin/jcmd even though man page /usr/lib/jvm/adoptopenjdk-
11-jdk-openj9/man/man1/jcmd.1.gz exists.
** This is probably a bug in AdoptOpenJDK and should be reported
upstream.
** Missing executable /usr/lib/jvm/adoptopenjdk-11-jdk-
openj9/bin/jinfo even though man page /usr/lib/jvm/adoptopenjdk-
11-jdk-openj9/man/man1/jinfo.1.gz exists.
** This is probably a bug in AdoptOpenJDK and should be reported
upstream.
** Missing executable /usr/lib/jvm/adoptopenjdk-11-jdk-
openj9/bin/jmap even though man page /usr/lib/jvm/adoptopenjdk-
11-jdk-openj9/man/man1/jmap.1.gz exists.
** This is probably a bug in AdoptOpenJDK and should be reported
upstream.
** Missing executable /usr/lib/jvm/adoptopenjdk-11-jdk-
openj9/bin/jstat even though man page /usr/lib/jvm/adoptopenjdk-
11-jdk-openj9/man/man1/jstat.1.gz exists.
** This is probably a bug in AdoptOpenJDK and should be reported
upstream.
** Missing executable /usr/lib/jvm/adoptopenjdk-11-jdk-
openj9/bin/jstatd even though man page
/usr/lib/jvm/adoptopenjdk-11-jdk-openj9/man/man1/jstatd.1.gz
exists.
** This is probably a bug in AdoptOpenJDK and should be reported
upstream.我尝试过运行Spring工具包，到目前为止没有出现任何问题。
我应该为此担心吗？如果有什么我可以做的来修复这些丢失的文件，请告诉我。我对jvm的工作原理知之甚少。提前谢谢你。

除非您需要jinfo、jstat或jstatd，否则您可以安全地忽略来自更新替代选项的那些警告(这些命令不是由OpenJ9提供的)。我打开了一个问题1，建议只为提供的命令包含手册页。
请注意，在较新版本的OpenJ9中添加了jcmd和jmap。
