XWorkList objects unable to be accessed via Velocity templates

Issue Summary

Objects of type com.opensymphony.xwork.util.XWorkList class are inaccessible from Velocity templates.

Steps to Reproduce

1. Define a public getter getMyList() on your Action class which returns an XWorkList
2. Call that getter and access a list item in your Velocity template using $myList.get(0) or $action.myList.get(0)

Expected Results

Return value displayed

Actual Results

Velocity error logged

Workaround

Define an alternative getter which returns a wrapped delegating instance of the XWorkList.

public class MyAction extends ConfluenceActionSupport {
    private XWorkList<Type> xworkList;

    public List<Type> getWrappedList() {
        return new ListWrapper<>(xworkList);
    }
}

public class ListWrapper<T> implements List<T> {
    private final List<T> delegate;

    public ListWrapper(List<T> delegate) {
        this.delegate = delegate;
    }
    
    // Implement interface methods that call delegate
} 

then access the wrapped instance in your Velocity template using:
$wrappedList or $action.wrappedList
