Hi Joris,
The <choice> construct in the schema might be the cause of the problem -
it's difficult to say since the current Xsd2Jibx code is really a mess.
Still, anything that causes this "Stack size mismatch" is a serious
problem in the binding compiler that should be fixed. Can you send me
the code do duplicate this problem (just the generated classes and
binding, not the original schema, and preferably with an Ant build.xml
to run it).
I'm hoping to get much better support for both code generation from
schema and JAXB conversions (especially JAXB 2.0 conversions) within the
next month or two.

Hi,
I'm in the process of migrating jaxb code to jibx as part of a proof of concept
(performance
issues with JAXB).
We use the xsd2jibx tool to generate the Java code and binding xml files. All
schemas are parsed
correctly, but the binding-compiler chokes on one. I put some work into
finding the cause of the
error and trimmed the XSD to the bare minimum, while still getting the error.
Is this a known bug? Can I get around it without changing the XSD?
XSD:
<?xml version="1.0" encoding="UTF-8" ?>

elementFormDefault="qualified"
