James Telfer updated ANN-438:
-----------------------------
Attachment: ann438.zip
Working (!) test case and configuration files.
As requested, a minimal test case. To determine if this error is reproducible, create an Eclipse project with the given source, compile and alter the hibernate.cfg.xml to suit your local db. The TestEntity is backed by a very simple table:
create table LookupCodes (
lookupType varchar(20) not null primary key
)
(Note the error should show before any table is required)
Part A) Hibernate Tools
Once all is configured, create a Hibernate Tools configuration that uses the hibernate.cfg.xml provided and start it. It should fail with the message described in the issue description above. Comment out the mapping file reference in the cfg.xml and the configuration will be able to create the SessionFactory.
Part B) JUnit
Run the test case using Eclipse with the mapping.xml included in the hibernate.cfg.xml. This works for me.
I am now using b7 of Hibernate Tools, and my runtime classpath (used by JUnit) has Hibernate 3.2 cr2 and Hib Annotations 3.2.0 cr1. As mentioned in the issue, Eclipse is running on the JDK 1.5.07 server VM with parallel GC enabled. Eclipse is using the JDK 1.5.07 client VM.
Note that my application failed in Tomcat while it was running on the JRE 1.5.07 client VM (so it's not just Hibernate Tools), but started working when I shifted it to the JDK server VM. I have no idea why this would make any difference.

> I created a class and annotated it with EJB 3 annotations, then created an XML descriptor to store my named queries. The XML I used is excerpted below. I then added the mapping file to my cfg.xml as a <mapping resource=""/%gt; element. When Hibernate was configured, it threw the parser exception included below also.
> The same error occurred when configuring my application within Tomcat (via Spring). To narrow down the problemI created a very simple class to configure Hibernate and ran that in Eclipse. This worked. The line used to configure Hibernate was: <code>new AnnotationConfiguration().configure(new File("hibernate.cfg.xml")).buildSessionFactory();</code>.
> Eclipse is running on Windows using the JDK 1.5.07 Server VM with parallel GC and the Eclipse runner used the JDK server VM with standard GC. Tomcat was using the JRE 1.5.07 client VM. I changed the VM used by Tomcat and it succeeded. Hibernate Tools still fails to read the configuration file.
> If any further information is required, I'd be happy to provide it. There is a forum thread (http://forum.hibernate.org/viewtopic.php?p=2310540&sid=f14052739a96c418c3fb6ec5cde5283d) that describes a similar problem, but the user's fix is not feasible in this scenario.
