             Summary: CNFE for a class implementing a taglib function
                 Key: WFLY-1529
                 URL: https://issues.jboss.org/browse/WFLY-1529
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 8.0.0.Alpha2
            Reporter: Juergen Zimmermann
            Assignee: Stuart Douglas


I'm using the latest WildFly snapshot containing Undertow 1.0.0.Alpha19. When I implement a JSF taglib having 1 function, then I get the stacktrace below when the .war file is deployed. This feature works fine with EAP 6.1.

The JSF function is implemented in de.shop.util.JsfFunctions and declared in WEB-INF/shop.taglib.xml as follows:
<?xml version="1.0" encoding="UTF-8"?>
<facelet-taglib xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facelettaglibary_2_2.xsd"
	version="2.2">
	<namespace>http://shop.de</namespace>
	<function>
		<function-name>aktuellesDatum</function-name>
		<function-class>de.shop.util.JsfFunctions</function-class>
		<function-signature>
			java.util.Date aktuellesDatum()
		</function-signature>
	</function>
</facelet-taglib>

The stacktrace in the WildFly console:
