FileNotFound when %APPDATA% points to Network Share

Environment

• Windows 10
• JDK 17
• Visual Studio Code version: 1.70.1
• Java extension version: v1.9.0

Steps To Reproduce

1. Set $env:APPDATA to point to network share, i.e.
   \dem3788.company.net\CENXXXVOL001\Profiles\UserName\AppData\Code\User\workspaceStorage\993565304d52f777ea974b4a582d4774\redhat.java\jdt_ws.metadata.plugins\org.eclipse.core.resources.projects\jdt.ls-java-project.project
2. Open Folder containing java project

Current Result

Expected Result

if $env:APPDATA points to a Drive:\Folder vs network share (\network\folder) project opens without errors

Additional Informations

先从 ProjectsManager.createJavaProject 中的项目初始化路径和 FileSystemResourceManager 的堆栈跟踪条目入手，然后在本地驱动器和网络共享上使用 APPDATA 进行复现。在两种 APPDATA 配置下打开 Java 项目都不会出现 FileNotFound 错误，即表示完成。
