    Class loading problem

    Stuart Douglas Master

      I am getting the following error intermittently after a hot deploy. If I redeploy enough it will always occur and then I have to restart the App server. I get the error with both jrocket and hotspot JVM, however it appears to be much more common running on hotspot.
      Does anyone know what could be causing this?
