I checked with the Microsoft team that maintain the Java Debugger in VS Code. The JDI implementation comes from the Eclipse JDT project. The summary is that the VS Code debugger doesn't allow final fields to be modified. It checks if the field is final so it won't call ObjectReference::setValue for final fields.
