OpenJDK on MacOS

[wingman]

I have set up openjdk 11 with home-brew, symlinking /usr/local/opt.openjdk@11/libexec/openjdk.jdk/ to /Library/Java/JavaVirtualMachines/openjdk-11.jdk/

I can run java in the terminal and other software can find the JDK/JRE. Libreoffice 6.3 does not detect a java environment. I have tried manually specifying the location, but /Library/Java/JavaVirtualMachines/ nor /Library/Java/JavaVirtualMachines/openjdk-11.jdk/ nor usr/local/opt.openjdk@11/libexec/ nor /usr/local/opt.openjdk@11/libexec/openjdk.jdk/ are recognized.

How can I have LibreOffice use the openjdk environment? Is it possible at all, if not, why not?

Hi, and welcome to the forum.

Libreoffice 6.3 does not detect a java environment.

Note that you must restart the suite after installing Java. I use neither LibreOffice nor JDK but you can read advice about using JRE if you need Java to work.

Thank you for responding.

I had read the documentation, but I see no reason why it does not work with openjdk, as LibreOffice works with openjdk on other platforms.

What could cause this issue? other software works fine with openjdk 11 and the java environment is set up normally. Is LibreOffice for macOS hardcoded to only use oracle's java versions?

You could manually enter the path to the Java in /Preferences /Options OpenOffice : Java

The entry might be something like /usr /lib /jvm /java-11-openjdk-something

I had tried that already, and have tired again, but is does not work. I have no idea why, that there is a symlink to reach the path is the only obvious difference with the oracle jdk (except of course the differences inherent to openjdk vs oracle jdk). Permissions are correct and the directory structure of the jdk looks identical.

I'm not a Mac user, so can only make a wild suggestion. From memory, some versions of macOS require Oracle Java 6 installed before they will recognise later Java versions; whether this is so in your case, I cannot say. But you need advice from an experienced Mac user, not from me.

OpenJDK is working fine for other applications. I have now installed the OracleJDK in parallel, which is recognized by other applications as well as LibreOffice.

Specifically LibreOffice appears to have issues with openjdk, no other application I have tested.

Look at these LibreOffice issues, perhaps starting with 101956. Remember that this is a user-to-user forum. You won't find developers here. I am done helping with this topic.
