OpenJDK 16 in java.home not recognized

I installed openjdk 16.0.1 via homebrew, and set corresponding path in java.home, but under "Java Tooling Runtime" tab of "Configure Java Runtime" page, nothing is not listed. FYI, I also have another two jdk 8 installed, and both 3 are written to java.configuration.runtimes, but "Installed JDKs" tab only shows those two jdk 8 installation.

Environment

• Operating System: macOS Big Sur 11.2.3 (on Apple Silicon)
• JDK version: installed path says 16.0.1, but java -version says 17, brew info openjdk says it's 17 preview
• Visual Studio Code version: 1.56.2 (Universal)
• Java extension version:

Some lines from settings.json:

    "java.home": "/opt/homebrew/Cellar/openjdk/16.0.1",
    "java.configuration.runtimes": [
        {
            "name": "JavaSE-16",
            "path": "/opt/homebrew/Cellar/openjdk/16.0.1",
        },
        {
            "name": "JavaSE-1.8",
            "path": "/Users/luzepu/Library/Java/JavaVirtualMachines/azul-1.8.0_292/Contents/Home",
            "default": true
        },
        {
            "name": "JavaSE-1.8",
            "path": "/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home"
        }
    ],

java -version outputs:

Beginne mit den Runtime-Einträgen in settings.json und der Seite Configure Java Runtime. Vergleiche anschließend den konfigurierten Homebrew-Pfad mit der gemeldeten Ausgabe von java -version und brew info openjdk. Reproduziere die Liste Installed JDKs und ermittle, ob der Pfad ausgelassen wird, weil er eine andere JDK-Version als sein Konfigurationsname enthält; abgeschlossen ist die Aufgabe, wenn die beabsichtigte Runtime korrekt aufgelistet wird oder die Abweichung eindeutig gemeldet wird.
