Description

A NoClassDefFoundError is raised when using the commonsValidator component with a non-jsp2.1 container + JSF RI1.2 + Facelets. This is caused by calls to UIComponentTag.isValueReference() - deprecated in 1.2 and should only be used by JSP tags.

A similar issue was reported by Ryan Lubke for the MyFaces Tomahawk project:
https://issues.apache.org/jira/browse/TOMAHAWK-589

The attached patch contains the same method contributed by Ryan to Tomahawk. Similar changes should be made to a few other places in shale-clay and shale-core where the aforementioned method call is also used where it needn't be.

stacktrace follows:
