Hi, I don't know if there is an issue with the GA, but you are relying on introspection to find your bean properties; that is asking for trouble IMO.
Always use property whitelisting to achieve a stable set of properties for your grids. Basically make sure to "include" the properties you want to show. (If you are not using include, a number of things can go wrong like: the Degree class may evolved, the hibernate stuff may have added extra runtime properties that the introspector is picking up, the JDK version may have changed which means that the introspector behavior may have changed, new data type analyzers may have been added etc.) -- Chris On Mon, Dec 14, 2015 at 2:31 AM, Vangel V.
