Discussion on: MacOS users, Java problems in Big Sur? HELP

Here's what I've found out so far:

  • If you're already using Java 15 everything works fine (tested with AdoptOpenJDK 15, installed with homebrew). Big Sur's /usr/libexec/java_home will detect Java 15 and set appropriate environment variables.

  • However /usr/libexec/java_home does not find Java 11 (tested with AdoptOpenJDK 11, installed with homebrew). Reinstall has no effect. Calling /usr/libexec/java_home -v 11 returns the path of Java 15. So yes, this seems to be broken in the shell. But IDEs with their own JDK configuration like IntelliJ are still able to use Java 11.

I haven't tried other versions than AdoptOpenJDK 11 and 15, but I guess they will behave like 11. Also note that I'm using homebrew to install all my developer tools and homebrew currently says:

Sorry, but it doesn't work .. with JDK 15 the NetBeans installer still can't find the JDK.
