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. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539482#539482] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
