Web Module getDocumentBase() Returns null

### Apache NetBeans version

Apache NetBeans 28 latest release candidate

### What happened

When loading my web app projects (which use a small subset of EE technologies) a NullPointerException is thrown when attempting to load the webapp components. As such, those components are not directly accessible in NetBeans. Here is the stacktrace...
