The PortletEnvironmentRenderRequest attempts to cast the list values of portal properties to a LinkedList. In WebSpace 10.0.7 (based on Liferay 5.2.3), the underlying implementation is actually an ArrayList, resulting in a ClassCastException. We should cast to a List interface instead of the LinkedList implementation.

Caused by: java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.util.LinkedList
