[Resteasy-users] Error marshaling w/ XmlAnyElement + Element Adapter - simple JBoss 7 + RESTEasy project

[Johnson, S. [USA] <joh...@ba...>]

Hi All,
First post, long-time lurker.  I have posted this same question to StackOverflow and not had any bites yet.  I've broken the issue down to the bare essentials – but I'm fairly clueless about where to go next.  I have posted the code here:  https://bitbucket.org/johnson_shawn/stackoverflow-21471310 – Basically I'm trying to take a label/value object list and marshal it to <XmlElementName label="Human Readable Label">Value Goes Here</XmlElementName>.  In a larger project with a crazy class path, it runs fine from the main.  When run through JBoss+RESTEasy I get the following (partial) stack:

INFO [stdout] org.jboss.resteasy.plugins.providers.jaxb.JAXBMarshalException: javax.xml.bind.MarshalException 21:02:19,959
INFO [stdout] - with linked exception: 21:02:19,959

Any ideas for debugging further or other brilliant answers will be greatly appreciated!
