StackOverflowError in WadlBuilder.generateResource

I have a resource at path A that defines a sub-resource locator at path B. When calling HTTP method OPTIONS on my sub-resource, WadlBuilder.generateResource enters an infinite loop because when it attempts to build the B child resource for resource A, it uses the locator that points to path A, including a child that uses A's path. When that child is processed while attempting to build B, A is processed again, resulting in B being processed again, etc.
Since there is no proper equals method on Resource, visited resources are never matched.
