[XALANJ-2203] ClassCastException when calling XPathExpressionImpl.evaluate with item argument of type NodeList

Description

When calling XPathExpressionImpl.evaluate(Object item, QName returnType), if item is of type NodeList, a ClassCastException is thrown.

I've looked at the source code. The problem seems to happen in XPathExpressionImpl.eval(Object contextItem). There is a section of code that reads:

Node contextNode = (Node)contextItem;
// We always need to have a ContextNode with Xalan XPath implementation
// To allow simple expression evaluation like 1+1 we are setting

The type cast is what causes the exception. Is there a fix or a work-around for this?
