[infinispan-issues] [JBoss JIRA] (ISPN-8946) All collection wrappers should always delegate to underlying collections where available

William Burns commented on ISPN-8946:
-------------------------------------

I have to rethink this as write operations will not work without first obtaining the lock to the cache in the LOCAL or INVAL cases (REPL/DIST/SCATTERED) would be fine as they always delegate to the cache, unless CACHE_MODE_LOCAL is supplied (which has many issues with write operations on these caches anyways).

> All places that override values returned from keySet and entrySet should always delegate appropriately to the underlying keySet or entrySet. We should try to be as minimally invasive to each level down as possible. An example would be that we shouldn't create copies of said collections if possible and instead just use delegates.
