switch exhaustiveness check not working within deconstruction pattern

issue にあるネストされた deconstruction-pattern switch を、記載されている VS Code と Java の環境で再現し、Extension の診断結果と純粋な javac の結果を比較します。「A switch expression should have a default case」という診断がどこで生成されるかを追跡します。完了条件は、網羅的な例がその診断なしでビルドでき、実際に非網羅的な switch では引き続きその診断が報告されることです。

Build fails on missing default case, even though switch is exhaustive.

Environment

• Operating System: Windows 10
• JDK version: 19
• Visual Studio Code version: 1.73.1
• Java extension version: 1.12.0
• Java Debugger extension version: 0.46.0

Steps To Reproduce

make (exhaustive) switch expression with nested deconstruction pattern
build fails -> "Add default case"

Example:

package dev.redio;

import static dev.redio.Main.Activity.*;

public class Main {

    public static void main(String[] args) {
        record Pair(boolean weekend, Activity activity) {}
        var pair = new Pair(true, new Sleeping(8));
        var msg = switch (pair) {   // <- A switch expression should have a default caseJava(1073743531)
            case Pair(boolean b, Sleeping s) -> "3";
            case Pair(boolean b, Skiing s) -> "4";
            case Pair(boolean b, Coding c) -> "5";
        };
        
        System.out.println(msg);
    }

    sealed interface Activity {
        record Sleeping(int hours) implements Activity {}
        record Skiing(String resort) implements Activity {}
        record Coding() implements Activity {}
    }
    
}

Current Result

Build Error (A switch expression should have a default caseJava(1073743531))

Expected Result

Build Success(Switch is exhaustive since all nested deconstruction possibilities are covered)
