Your previous answer seems to point to the culprit being the call to the third party software - as you don't have the source then maybe you should contact the third party to see if they can shed some light on this issue.
I doubt the issue is Struts messing up the reference of the ActionForm passed to the Action's execute method or stored in the Request - it might be because of whats configured in your struts-config.xml or what you have in the <html:form> element of your jsp not being right. But that wouldn't add up with what you say is happening after the http client call - and theres nothing to indicate any issue in the snipets of code you've posted. Sorry, I'm out of ideas.
