-------------------------------------

Hi, we had the exact same issue. However, is it possible that appending this library to the pre-classpath leads to other side effects? What if the class used by Weblogic conflicts with the one in the pre-classpath? Can we be sure that the Weblogic server instance will not shutdown or have any other problem by applying this workaround?

Thanks in advance.
