"Unable to load Java Runtime Environment" when starting SQLWorkbench/J

I get Unable to load Java Runtime Environment when starting SQLWorkbenchJ.app.

I'm on macOS Catalina 10.15.2, and I installed the app with brew cask install sqlworkbenchj. My JDK 8 is installed using brew install adoptopenjdk8.

How do I solve this problem? SQLWorkbench/J does not provide any other helpful messages, even when I start it with open -a in the Terminal.

Solution

  • Luckily I found a hint on SQLWorkbench/J's forum

    The fix was to add ...

    <key>JVMRuntime</key>
<string>adoptopenjdk-8.jdk</string>

    ... to /Applications/SQLWorkbenchJ.app/Contents/Info.plist, and create a symlink to JDK8:

    ln -s /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk /Applications/SQLWorkbenchJ.app/Contents/PlugIns/

    Voila!
