    Unable to load class sun.reflect.GeneratedMethodAccessor

    Helmien Steyn Newbie

      Hi,

      We have our application ear deployed on jboss 4.2.2. We have integrated GridGain into our application to grid-enable some of the methods. GridGain allows you to annotate a method and then it uses AOP crosscutting to interject grid logic for the method.

      Calling these methods works fine the first few times, but after a few invocations, jboss throws the exception below.

      I have posted to both JBoss AOP and GridGain forums, but so far nobody has been able to help.

      Any help will be appreciated.
