switch exhaustiveness check not working within deconstruction pattern

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)

Additional Informations

Compiles with pure javac without errors

在列出的 VS Code 和 Java 环境中复现 issue 中的嵌套解构模式 switch，并将扩展的诊断结果与纯 javac 进行比较。追踪“A switch expression should have a default case”诊断在哪里产生。完成标准是：穷尽示例能够在没有该诊断的情况下构建，同时真正非穷尽的 switch 仍然报告该诊断。
