Description

FuncSystemProperty.execute() can fail with NPE when processing the line:

if (namespace.startsWith("http://www.w3.org/XSL/Transform")

because "namespace" can be null.

To reproduce:

org.w3c.dom.Node node = new org.apache.xerces.impl.xs.opti.DefaultDocument();
org.apache.xpath.XPathAPI.eval(node, "system-property('xsl:version')");
