[infinispan-issues] [JBoss JIRA] (ISPN-7668) Merge implementation is not correct on SimpleCache

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 Fix For: 9.0.0.Final 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.
