[infinispan-issues] [JBoss JIRA] (ISPN-1990) Preload sets the versions to null (repeatable read + write skew)

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762576#comment-12762576 ] 

Galder Zamarreño commented on ISPN-1990:
----------------------------------------

This is fundamentally broken since the CacheLoaderManager cannot preload the cache putting an entry with its corresponding version (even if that can be stored as such). IOW, there's no Cache.put() that takes a version. This will be resolved as part of ISPN-2281, so will re-evaluate once that is fixed.

> I think I've spotted a issue when I use repeatable read with write skew check and I preload the cache.
>  
> I've made a test case to reproduce the bug. It can be found here [1]. 
> The problem is that each keys preloaded is put in the container with version = null. When I try to commit a transaction, I get this exception:
>  
> {code}
>  java.lang.IllegalStateException: Entries cannot have null versions!
