>          Issue Type: Bug
>    Affects Versions: 6.6.0
>            Reporter: Jon Pulice
>            Assignee: Lukasz Lenart
>            Priority: Minor
>             Fix For: 6.9.0, 7.2.0

> Since 6.6.0, the ProxyUtil class now always uses the WTLFU cache type when 
> creating its two internal caches. This means that the caffeine 
> library is now mandatory when it was not before.
> {code:java}
>   private static final OgnlCache<Class<?>, Boolean> isProxyCache = (new 
> DefaultOgnlCacheFactory(10000, OgnlCacheFactory.CacheType.WTLFU, 256))
>     .buildOgnlCache();
>   private static final OgnlCache<Member, Boolean> isProxyMemberCache = (new 
> DefaultOgnlCacheFactory(10000, OgnlCacheFactory.CacheType.WTLFU, 256))
>     .buildOgnlCache();{code}
>  
> Prior to 6.6.0, setting both of these configuration options would allow you 
> to omit the caffeine dependency from an application:
> {code:java}
> <constant name="struts.ognl.expressionCacheType" value ="basic" />
> <constant name="struts.ognl.beanInfoCacheType" value="basic" />{code}
>  
> Would it be possible to allow for the cache type used by the ProxyUtil class 
> to be configurable as well similar to the above?
