Visual Studio Code showing "Java 11 or more recent is required to run. Please download and install a recent JDK"

Issue

Today Visual Studio Code started showing me a pop-up saying:

Java 11 or more recent is required to run. Please download and install a recent JDK.

I need to use the JDK 8 (working on Apache Beam and that's the last supported version). I have been working on that and haven't had any issues until this came up.

I have read through this article and implemented the points mentioned there.

Here is my workspace settings on Visual Studio Code (I have double-checked the paths)

{
    "java.configuration.updateBuildConfiguration": "disabled",
    "java.home": "/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home",
    "java.configuration.runtimes": [
        {
          "name": "JavaSE-1.8",
          "path": "/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home",
          "default": true
        },
        {
          "name": "JavaSE-11",
          "path": "/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home",
        }
      ]
}

Other helpful information:

➜ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

and

➜ which java
/usr/bin/java

This started happening today even though I have been running JDK 8 on Visual Studio Code successfully for a while now. I don't remember updating Visual Studio Code, so I'm not sure as to why this is being displayed now since apparently the pop-up has been displayed since mid-April (asked on the vscode-java Gitter channel).

Solution

Change from

"java.home": "/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home"

to

"java.home": "/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home"

and keep the rest of the settings as is.
