Code Workspace Classpath is corrupted after restart

1. When I open a code-workspace with a clean Java Language Server Workspace everything works.
2. Once I restart VSCode and open any file, I get the following warning SomeJavaClass.java is not on the classpath of project workspacename+some_random_hash, only syntax errors are reported
3. When I execute Java: Clean Java Language Server Workspace we are back at 1.

Environment

• Operating System: Windows 10
• JDK version: 16.0.1.9
• Visual Studio Code version: 1.56.1
• Java extension version: 0.79.1

Steps To Reproduce

1. Create a test.code-workspace file with the following contents:

   {
       "folders": [
           {
               "path": "test"
           }
       ]
   }
   

2. Create folder test
3. Create a file Test.java in that folder
4. Open the code-workspace with VSCode
5. Open test/Test.java in VSCode
6. Everything works
7. Execute Developer: Reload Window or restart VSCode
8. Open test/Test.java in VSCode
9. This Error appears and nothing works
10. Execute Java: Clean Java Language Server Workspace and restart VSCode
11. Everything works

Current Result

A restart of VSCode breaks the Java Language Server Workspace and Classpath

Expected Result

It shouldn’t

Additional Informations

Yes, the change appears to resolve the issue. Cleaning the language server workspace, or reloading the window continue to work as well with the snippet provided.

This will be fixed in 0.79.2, which we expect to have out early next week. Feel free to re-open the issue though if the problem does persist.

This should be fixed by https://github.com/eclipse/eclipse.jdt.ls/pull/1767 I guess. @snjeza @rgrunber
