Hello all,
I tried to run a very simple Vaadin application in WebSphere v8.0.0.2 that only has a very simple form. I am using Vaadin v6.7.4. The first time I load the application into the browser it throws the exception shown below. This exception is only shown only the first time and on other requests the application works normally. Any advice would be appreciated.
terminalError An error occurred java.lang.ExceptionInInitializerError
