I'm seeing an exception, seemingly inside some sun classes, when trying to compile an xml schema.
I've compiled this schema many times before, so I don't suspect the schema of being problematic. I think something may have changed in my java VM, perhaps with the latest upgrade. I have no doubt that upgrading to jaxb 2.0 would fix the problem, since I tried it. However, we have to stick to jaxb 1.0 due to a bug in the JAXB-RI XJC.
Macbook: ant -f build-response.xml
Buildfile: /Users/matt/workspace/resources/build-response.xml
compilexjc:
[echo] Compiling the schema...
[xjc] Compiling file:/Users/matt/workspace/schemas/response/partner_response.xsd and others
