number() function doesn't work correctly on Boolean variable

           Summary: number() function doesn't work correctly on Boolean
                    variable
           Product: Commons
           Version: 1.1 Final
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: JXPath
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: sm@jacada.com


When running the number() function on a Boolean variable, as in the following 
code:
        JXPathContext context = JXPathContextFactory.newInstance().newContext
(null, null);
        Variables vars = new BasicVariables();
        vars.declareVariable("bool", new Boolean("true"));
        context.setVariables(vars);
        Number num = (Number)context.getValue("number($bool)");
        System.out.println("num = " + num);
The value returned is NaN, instead of 1.0, as per the XPath spec.
