Description

Application classloader looks in WAR's WEB-INF/lib before WEB-INF/classes. This is in violation of servlet 2.4 (and 2.3) specification, 9.5 Directory Structure, which states:
"TheWeb application class loader must load classes from the WEB-INF/ classes directory first, and then from library JARs in the WEB-INF/lib directory."

This behaviour prevents web application from overriding classes and resources from included libraries.
