[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4070) createProxy() called even when hasProxy() returns false

[Philip Borlin (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Philip Borlin updated HHH-4070:
-------------------------------

    Attachment: HHH4070.mapping
                HHH4070.java

Attached is the test file and mapping as requested.  The test file has a standard main method so it can be run from the command line.  Depends on hsqldb but that can be changed to a database of your choice by modifying the setupDatabase() method.  HHH4070.java is in the default package.

Here is the stacktrace that I get when I run the file:

>    Affects Versions: 3.3.2

> This problem occurs when an EntityTuplizer is used.  In my case I throw an UnsupportedOperationException in my createProxy() method.  I would expect that would be ok since my hasProxy() method returns false.  This was working in 3.3.1 but broke in 3.3.2.
> In DefaultLoadEventListener in the proxyOrLoad() method there is a call to persister.hasProxy().  This makes a call to AbstractEntityPersister which simply checks to see whether the entityMetamodel isLazy().
> That check succeeds since lazy is sent to true.
> The next check sees if isAllowProxyCreation() is false in the options.
> Lastly creatProxyIfNecessary() is called which if the entity does not exist calls createProxy() on the persister.  AnstractEntityPersister delegates this directly to the tuplizer.
> At no point was the tuplizer's hasProxy() method ever consulted.
