Setting up binding takes time here, spent in getting BeanInfo-s. Either a GUI form with complex hierarchy of bean classes, or overall overloaded computer (can see parsing running all the time of the snapshot as well). The whole execution is spent inside the Beans Binding library, so we can't do anything about this. Since it all is happening as part of form loading, from the point of view of UI responsiveness this is bug 179407 (i.e. that the form loading is blocking UI).
