createProxy() called even when hasProxy() returns false
-------------------------------------------------------
Key: HHH-4070
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4070
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.2
Environment: 3.3.2GA, PostgresQL 8.3
Reporter: Philip Borlin
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.

Please attach a runnable test case (Java + mapping) that reproduces this issue.

-------------------------------
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:
Exception in thread "main" java.lang.UnsupportedOperationException: Does not
support proxies

I attached a test case almost 4 months ago. Can the status be changed from Awaiting Test
