</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>This turned out to be due to javax.xml.bind.annotation.XmlRootElement coming from the system classloader while the jboss-reflect classes coming from a child classloader. It was set up to always use the classloader of the class we are creating an accessor for. I have changed it to still do that apart from if the class comes from a parent classloader of the jboss-reflect one, in which case we use the jboss-reflect classloader.</p></div>
