Detached entity not reported consistently
-----------------------------------------

                 Key: EJB-368
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-368
             Project: Hibernate Entity Manager
          Issue Type: Bug
          Components: EntityManager
    Affects Versions: 3.3.2.GA
         Environment: ejb3-persistence-1.0.1.GA.jar
hibernate-entitymanager-3.3.2.GA.jar
hibernate-3.2.6.ga.jar
postgresql-8.3-603.jdbc3.jar
jdk 1.5.0_13/jdk 1.6.0_06
Windows XP
            Reporter: Henriette Harmse
         Attachments: HibernateTest.zip

The attached code does not fail consistently with a "detached entity" exception. 

Under jdk 1.5 (tested with jdk 1.5.0_10 & 1.5.0_13) it fails with a detached entity exception which is correct. Running the same code against jdk 6 (tested with jdk 1.6.0_06 & jdk 1.6.0_03) passes and the records are written to the database.

The same code works against jdk 1.5 (and jdk 6) as well when the <mapping-file>META-INF/emailAddress.xml</mapping-file> and <class>example.domain.EmailAddress</class> are commented out from the persistence.xml file. 

The fact that this code does not fail consistently could cause developers to use Hibernate incorrectly which may only be apparent much later into the project.

In order to run the example:
1. Create Postgres database called "example".
2. Create "example" user with username and password "example"
3. Edit the run.cmd and build.cmd files to set your JAVA_HOME.
4. Run "build.cmd".
5. Run "run.cmd".
