the method call getObject(...) on a previous version throws an IncorrectPersistentClassException
------------------------------------------------------------------------------------------------

                 Key: JCR-1426
                 URL: https://issues.apache.org/jira/browse/JCR-1426
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-ocm
    Affects Versions: core 1.4.1, 1.4, 1.4.1, 1.5
            Reporter: Christophe Lombart


The method call getObject(...) on a previous version of an persistent object throws the exepction

"IncorrectPersistentClassException  : type: nt:unstructured has no descriptor". 

This issue was dectected when a pojo is mapped into the nt:unstructured node type. In this
case, the mixin type ocm:discriminator has to be applied but it seems that is not present
in the previous version node.

Here is a exemple of a persistent class that can cause this issue : 

@Node(jcrType="nt:unstructured",
       jcrMixinTypes = "mix:versionable,mix:referenceable,mix:lockable")
public class Content {

   /** Node path in the CR */
   @Field(path=true)
   private String path;

   @Field(uuid=true)
   private String uuid;

   @Field(jcrName = "test:lastModified")
   private Calendar lastModified;

   /** content title */
   @Field(jcrName = "test:title")
   private String title = null;

   @Field(jcrName = "test:mimeType")
   private String mimeType;

   @Field(jcrName = "test:data")
   private byte[] data;

   ... getters + setters....
}
