> I have a class, let's call it A, that contains a List of class B. Each instance of B has a List of class C. I'm trying to generate the DDL for this, so I've annotated the code and run it through SchemaExport, which throws a ConcurrentModificationException. My environment: Java 1.5, Oracle 10, Hibernate 3.2.1ga.
> The problem seems to be caused by having an entity (A) containing an embedded collection (of B), each element of which contains a collection (of C). SchemaExport generates correct DDL when the annotations are modified to make B and/or C an entity, but not when they are both components. I realise this is considered something of an exotic case, but I'd like to know why the DDL doesn't generate.
> See bugReport.txt in attached zip for further details.
