Build Identifier: Eclipse Persistence Services - 2.2.0.v20110202-r8913

I am using EclipseLink for a Netbeans7 Java web application deployed onto Glassfish3.1, with Oracle 10g R2 backend.

I have a complex entity inheritance hierarchy essentially rooted at:

 @Entity 
 @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) //FAILS: 
 public class Element extends All_ {

Although this in turns extends All_ where:

 public class All_ implements Serializable {

Is a utility base class that merely provides some common logging services 

Access type property is used throughout the system.

I will provide an attachment with the full glassfish output log including stacktraces.

It is extremely difficult to sensible declare "Steps to reproduce" below without providing my entire quite large Netbeans code project for your examination.

I might add the reason I am exploring TABLE_PER_CLASS at all is that under SINGLE_TABLE we are running up against the 1000 column limit of Oracle, and under JOINED the system grinds to a halt on some crucial queries because of the many joins (under JOINED we have over 700 tables).


Reproducible: Always

Steps to Reproduce:
1. Undeploy all existing projects, ensure all existing tables in schema deleted, restart Glassfish3.1, set EclipseLink table creation strategy property name="eclipselink.ddl-generation" value="create-tables",

2. Rebuild entire web application ensuring base entity Element has @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)

3. Run Netbeans Java EE web application and immediately observe:
