Fixed by implementing the XPathFunctionCall.copy() method. Committed for 9.7 and 9.8.

Note: the problem occurs when a free-standing XPath expression is evaluated using the JAXP XPath API, and contains an extension function call to be resolved using the JAXP FunctionResolver mechanism. Such a function call is represented internally as an XPathFunctionCall node on the expression tree. All expression nodes are expected to provide a method to allow the expression to be copied when tree rewrites take place during optimization; the failure occurs because this method is not implemented.
