> ImportHandler is not importing classes in WEB-INF/classes and, thus, developers are unable to import classes into the EL evaluation environment per EL 3.0 spec. section 1.22.2 "Imports of Packages, Classes, and Static Fields"
> Here's the ImportHandler relevant code (https://github.com/jboss/jboss-el-api_spec/blob/master/src/main/java/javax/el/ImportHandler.java#L176)
> {code:java}
> private Class<?> getClassFor(String className) {
>     if (!notAClass.contains(className)) {
>         try {
>             return Class.forName(className, false, getClass().getClassLoader());
