While looking at my systems because of the log4j security issues I noticed the following:
I am running solr8 as part of my MacPorts mail server setup and it shows up like this: $ ps laxww|grep java 504 50615 50613 0 20 0 7594340 1316684 - S ?? 97:31.56 /usr/bin/java -server -Xms1g -Xmx1g -XX:+UseG1GC -XX:+PerfDisableSharedMem -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=250 -XX:+UseLargePages -XX:+AlwaysPreTouch -XX:+ExplicitGCInvokesConcurrent -Xlog:gc*:file=/opt/local/var/solr/logs/solr_gc.log:time,uptime:filecount=9,filesize=20M -Dsolr.jetty.inetaccess.includes= -Dsolr.jetty.inetaccess.excludes= -Dsolr.log.dir=/opt/local/var/solr/logs -Djetty.port=8983 -DSTOP.PORT=7983 -DSTOP.KEY=solrrocks -Duser.timezone=UTC -XX:-OmitStackTraceInFastThrow -XX:OnOutOfMemoryError=/opt/local/share/java/solr-8.9.0/bin/oom_solr.sh 8983 /opt/local/var/solr/logs -Djetty.home=/opt/local/share/java/solr-8.9.0/server -Dsolr.solr.home=/opt/local/var/solr -Dsolr.data.home=/opt/local/var/db/solr -Dsolr.install.dir=/opt/local/share/java/solr-8.9.0 -Dsolr.default.confdir=/opt/local/share/java/solr-8.9.0/server/solr/configsets/_default/conf -Xss256k -jar start.jar --module=http Which means that MacPorts solr8 runs using macOS native java and not one from MacPorts itself. I thought the MacPorts stuff was supposed to be fully independent (except for Xcode). $ java -version java version "12.0.2" 2019-07-16 Java(TM) SE Runtime Environment (build 12.0.2+10) Java HotSpot(TM) 64-Bit Server VM (build 12.0.2+10, mixed mode, sharing) $ ls -l /usr/bin/java lrwxr-xr-x 1 root wheel 74 Aug 10 2019 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java $ ls -l /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java -rwxr-xr-x 1 root wheel 58336 Jul 11 07:48 /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java That java is starting to get old, the last update was the last Security Update from macOS Mojave I also have Oracle Java SE 8 installed: $ /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version java version "1.8.0_311" Java(TM) SE Runtime Environment (build 1.8.0_311-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.311-b11, mixed mode) Basically, I am rather confused about java numbering. I know I have the latest Oracle Java install and that my macOS Mojave version had its last update in the summer of 2021. I am also somewhat confused about MacPorts using the standard macOS Java which has a higher number but is an older version. Can somebody enlighten me? And shouldn’t ports that use java not depend on a java that comes with (old, outdated) java’s in macOS? But install and use an open source version instead? Or use the one from Oracle if available?
