Removing the JRE System Library from Classpath

I'm unable to find a way to remove the JRE System Library from the project classpath.

Eclipse has generally had the ability to remove the System Library from classpath.

Environment

• Operating System: Windows 11 Beta (had issues on 10 as well)
• JDK version: 8 and 11 - both unable to remove
• Visual Studio Code version: 1.59.1
• Java extension version: v0.81.0

Steps To Reproduce

1. Open a project, and attempt to remove the JRE System Library.
2. This is not possible.

A "sample" project is available at https://github.com/VivoKey/vk-u2f. The error itself is on loading CTAP2.java.

Current Result

Unable to remove JRE System Library

Expected Result

To be able to remove the JRE system library

Additional Informations

The requirement to remove JRE System Library is for programming in JavaCard, which does not use the standard Java libraries but provides it's own. I've been ignoring the issue for a while but have now found an error where using an Exception class throws build errors in VS Code (the other builds work as normal, as they don't use the system library) due to the JavaCard library also providing a java.lang.Exception.

Riprodurre il problema con l’esempio collegato VivoKey/vk-u2f, concentrandosi su CTAP2.java e sul suo utilizzo della libreria JavaCard. Esaminare come è configurato il classpath del progetto Java ed eseguire la build del progetto per stabilire il fallimento attuale. Il lavoro è completato quando è possibile rimuovere JRE System Library e CTAP2.java viene compilato senza la classe standard Exception in conflitto.
