----------------------------------

             Summary: Merge implementation is not correct on SimpleCache
                 Key: ISPN-7668
                 URL: https://issues.jboss.org/browse/ISPN-7668
             Project: Infinispan
          Issue Type: Bug
          Components: Core
            Reporter: Katia Aresti
            Assignee: Radim Vansa


Merge method is not correctly implemented in SimpleCache.
Merge should work this way :
* if the key is not present, add the value
* If the key is present, apply the function between the existing key's value and the given value and replace the key with the merged result
* If the merge function returns null, remove the key

The case that should work as "putIfAbsent" does't work. Merge function is applied to null and the given value.
