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

Hello, i have been seen in your revision that in the class VersionManagerImpl 
you removed in method InternalVersionItem the condition that comprubes not to 
instert  null values in the attribute  "versionItems". Anywhere some times  
InternalVersionHistory cache's doesn't  have the find value and return null 
values and then when you try put in versionItem it throw NullPointerException. 
Why did you remove this condition, it's really ok?

        Thanks a lot:
            Jorge Rodríguez Pedrianes
