Maven projects not loading in VS Code after latest Language Support for Java by Red Hat Extension Update (v1.42.0)

マルチモジュール Maven プロジェクト、VS Code 1.100.2、extension 1.42.0、および settings.json の JDK 設定で再現します。まず Java Language Server のエラーとプロジェクトの .classpath/.settings ファイルから始めます。完了の条件は、Maven プロジェクトが正しく読み込まれ、java.lang.Object などの標準クラスが unbound JRE System Library なしで解決されることです。

After updating the Language Support for Java(TM) by Red Hat extension to version 1.42.0 (2025-05-19), my Maven Java projects no longer load properly in Visual Studio Code. The Java Language Server fails to resolve standard Java classes (e.g., java.lang.Object), and the Maven projects are not recognized or built correctly.

To Reproduce
Steps to reproduce the behavior:

1. Open a multi-module Maven Java project in VS Code.
2. Ensure the latest Language Support for Java(TM) by Red Hat extension (v1.42.0) is installed.
3. Set the JDK in VS Code settings (settings.json) to JDK 8, 11, or 21 (tried all):
   "java.jdt.ls.java.home": "valid\path\to\jdk"
4. Reload VS Code.
5. Observe that Maven projects are not loaded, and Java standard library classes cannot be resolved.

Error Logs

1. The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files
2. Unbound classpath container: 'JRE System Library [java-21-openjdk]' in project ...
