Lukasz Lenart commented on WW-4645:
-----------------------------------

In such case you won't be able exclude {{java.lang.Object}} as this will block everything. And now {{java.lang.Object}} is defined as an excluded class in {{struts-default.xml}}

> In the isClassExcluded method invoke targetClass.isAssignableFrom(excludedClass), that mean targetClass must be parent class of excludedClass or same as excludedClass. 
> How can enumerate all son classes in the excluded classes? 
> Why not opposite? I only prevent the parent class, all son classes also be prevented. 
> The EX: excludedClass.isAssignableFrom(targetClass)
