Let me know the steps to install Java on a Mac. Everything in /usr/bin is one of these wrapper thingies that looks at JAVA_HOME and then runs the binary it finds there. which javac to see what that actually runs you probably see /usr/bin/javac. There are wrappers for all the common commands ( javac, too). It uses JAVA_HOME to decide which java to actually run. JAVA_HOME decides which java is used by some things, but the java you get when you just type java is /usr/bin/java, and that executable is actually just a wrapper that picks a java to run from amongst all installed versions. The -v option is mostly for scripting, and that's how we're using it here). The -V option lists all and is meant for your eyeballs, not for scripts. here, assign it to the JAVA_HOME env var. (the backticks mean: Run this then take the output of it and treat that as the 'value' of the expression.

To 'override', you can use something like (depends on which shell you're using on your mac): export JAVA_HOME=`/usr/libexec/java_home -v 17`

To see all installed javas, you can run: /usr/libexec/java_home -V Also, yes, if you just run java without specifying which one you want, you so happen to get java13 here. the java8 to java9 transition broke a ton of stuff, much of it needless and much of it not reasonably expectable or fixable by libraries and apps, so a bunch of java apps and libraries only run on java8 - just an example). This is often required java is not backwards compatible (it tries to change little, but e.g. This change does not affect Web Start applications, it only impacts applets.ĭevelopers and System administrators looking for alternative ways to support users of Safari should see this blog regarding Launching Web Start applications.Java doesn't mind if you install multiple versions. Java applications are offered through web browsers as either a web start application (which do not interact with the browser once they are launched) or as a Java applet (which might interact with the browser). Apple's Safari version 12 and above have dropped support for NPAPI, and therefore Java Plugin do not work on these browsers anymore. The Java Plugin for web browsers relies on the cross-platform plugin architecture NPAPI, which had been supported by all major web browsers for over a decade.

Safari 12 and above no longer supports NPAPI (technology required for Java applets) This information is from Oracle, which states: Java and Apple Safari Browser - Oracle Thanks for visiting the Apple Support Communities and asking about Java in macOS Mojave 10.14.
