[infinispan-issues] [JBoss JIRA] (ISPN-4559) Replace fails with cache loader

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4559?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12987325#comment-12987325 ] 

Dan Berindei commented on ISPN-4559:
------------------------------------

Seems like a problem with all conditional commands, not just {{ReplaceCommand}}: {{RemoveCommand(value != null)}}, {{PutKeyValueCommand(putIfAbsent == true)}}.
The entry is also not retrieved if the command has the {{IGNORE_RETURN_VALUES}} flag, which is not correct for conditional commands.

> cache.replace(key, oldValue, newValue) compares the current value in the cache to oldValue, and if they differ it turns into a no-op.
> However, CacheLoaderInterceptor does not load entries for a ReplaceCommand. 
> If the entry only exists in the loader and not in memory, this causes the replace to fail.
> CacheLoaderInterceptor must always load the value for a ReplaceCommand.
