Title: DynamicJAXBContext issue

Hello,
we tried to use DynamicJAXBContext in order to build dynamic entities from xsd schema but we get the exception:

Caused by: Exception [EclipseLink-50040] (Eclipse Persistence Services - 2.3.0.v20110415-r9234): org.eclipse.persistence.exceptions.JAXBException

Libraries used:
- jdk 1.5.0_16
- EclipseLink 2.3.0.v20110415-r9234

We use DynamicJAXBContext in this way:

DynamicJAXBContext jaxbContext = DynamicJAXBContextFactory.createContextFromXSD(xsd.getInputStream(), null, null, null);

In class DynamicClassWriter source code, line 302, we found this check:

if (lastCount <= 5) {
  cv.visitInsn(ICONST[lastCount + 1]);
}

but ICONST is a 6 elements array.

At the moment we substituted <= with < and it works but we don't know if this is the right fix.

Thank you.
Daniele
