Java figures out which version to use from JAVA_HOME or /Library/Java/JavaVirtualMachines. Are you sure that’s not a MacPorts version?
My native macOS java binary runs the last LTS jdk from MacPorts: > sudo -u solr /usr/bin/java -version > openjdk version "11.0.13" 2021-10-19 > OpenJDK Runtime Environment Temurin-11.0.13+8 (build 11.0.13+8) > OpenJDK 64-Bit Server VM Temurin-11.0.13+8 (build 11.0.13+8, mixed mode) This is a simple path issue because `java` Is found in /usr/bin. If you want to use a MacPorts-installed binary, set up your paths appropriately. I’m not aware of any practical difference this would make. > port provides > /Library/Java/JavaVirtualMachines/openjdk11-temurin/Contents/Home/bin/java > /Library/Java/JavaVirtualMachines/openjdk11-temurin/Contents/Home/bin/java is > provided by: openjdk11-temurin > On Dec 12, 2021, at 18:19, Gerben Wierda via macports-users > <macports-users@lists.macports.org> wrote: > > Which means that MacPorts solr8 runs using macOS native java and not one from > MacPorts itself.
