javax.xml.stream.XMLStreamException: problem accessing the parser

I have an soap message receiver class that extends AbstractInOutSyncMessageReceiver. I use this class to handle my web service requests. Inside the invokeBusinessLogic(MessageContext, MessageContext) method, I am attempting to parse the envelope header first and then the body. The header contains an element called MultiSpeakMsgHeader and the body contains an element called PingURL. All the XML objects were created using XMLBeans. The web service works fine if I only attempt to parse the body's first element creating the PingURLDocument. If I try to parse the header's first element creating the MultiSpeakMsgHeaderDocument, that works fine, but right afterwards if I try to parse the body's first element I get an exception: XMLStreamException: problem accessing parser.

Am I doing something wrong? If so, any help would be appreciated. If not, is this a known bug/issue? And is there a work around? Also I wasn't sure if this is the right place to submit questions. What is the normal procedure for submitting questions or possible bugs?

Include below are three files that may or may not be helpfull. (1) The AbstractInOutSyncMessageReceiver java file. (2) The skeleton java file that handles the service. And (3) the xml I'm sending to the server. As I mentioned above, everything works fine if I don't attempt to read the header. As a side note, the reason I need to read the header is to check for a valid user id and password. If there is another way to check/validate header information, I'm open to suggestions.
