Hi, Jeremy,
Did I understand right that app was working fine with JDK6 and the
problem appeared only with JDK7?
There are several things we can do:
1) You can try to use the newest JAXB release 2.2.6. May be a bug is
fixed already:
http://jaxb.java.net/2.2.6/
2) You can provide that objects for which you were trying to create
JAXBContext. And I'll try to find the problem.

I am running into a problem that is mysterious... if I debug it I can get it to work, but if I let it just run, it always fails on some property. Here is the stack trace of the failure. It seems like an iterator is trying to get an element that has already been consumed. Can you help me determine what is the problem here? What can I change to fix this? Let me know if I can provide any additional information about the object that fails. I am kind of new to this but I know that there is the WSDL file and the actual XSD schema, and the "ref" elements are part of the schema. This object is failing to even generate that schema, and it seems on the ref elements. Another thing is that it feels like this is threading related because if I do a clean build, parts of the stack trash "smash" each other due to not having synchronization on System.out. I have an example of a smashed stack tra!
ce output
below the cleaner stack trace showing the issue. Any help is greatly appreciated.
