Description

I am using VS Code and I would like to experiment with the new features of Java 21. However, I am not sure how to set the java version to 21 and turn on the compiler preview options in the Java extension. It would be helpful if the language level and preview options were available in the “Configure Classpath” webview.

Research direction

Start by locating the “Configure Classpath” webview entry point in the VS Code Java extension and inspect how its current options are represented and applied. Done means the webview exposes Java language-level and compiler preview settings that users can configure for Java 21 experimentation.
