-------------------------------------
David,
What command-line options are you using to invoke the XSD2JavaGenerator in this context?

> When I attempt to generate the java source files representing the SDOModel, I am seeing a NPE thrown in SDOXSDEcoreBuilder.java. Here is the stack trace:
> java.lang.NullPointerException

> I've tracked the issue down to some code changes made for T-513. A change was made in XSDHelperImpl in the define method to change how the ResourceSet is constructed prior to loading the schema. Additional changes were made in SDOXSDEcoreBuilder to set up some options when constructing a ResourceSet. These combined changes seem to be precipitating the issue. The XSDSchemaAdapterFactoryImpl inner class contains a method isFactoryForType(Object) that appears to be setting up conditions such that more elementDeclarations than should be expected is being created, later leading to the NPE.
