> Spring 2.0.6, Hibernate3
> Reporter: Judy L
>
> We have an application using Struts 2.0.9 and running in WebSphere 6.1.0.2
> under Linux environment. Occasionally, following ParametersInterceptor
> exception is thrown when the application is started in WAS. After restarting

> type of problem has been fixed in the newer Struts 2 version? Many thanks!!
