Invalid runtime for JavaSE-20: Runtime at '/usr/local/opt/jdk-20.0.2.jdk/Contents/Home' is not compatible with the 'JavaSE-20' environment.

[zl03jsj]

my coc-settings:

  "java.configuration.runtimes": [
    {
      "name": "JavaSE-20",
      "path": "/usr/local/opt/jdk-20.0.2.jdk/Contents/Home",
      "default": true
    }
  ]

and my jdk directory here:

The version of coc-java is v1.15.2.

According to README.md, coc-java comes with bunlded jdt.ls from 1.14.0, which not support JDK 20/21.

So we can download latest jdt.ls manually and set "java.jdt.ls.director": "/path/to/your/jdt" at coc-settings.json.
