The attached snapshot does not show the reported 20s but only 8s in AWT Event Queue thread. Most of it spent in org.jdesktop.beansbinding.Binding.bind(), specifically in constructing BeanInfos for related component classes. It's probably rather unusual taking so much time, it depends on the complexity of the bean classes used in the binding and number of bindings. Same work needs to be done in runtime. So this is related to the internals of the beansbinding library, don't think we should try to workaround in in the IDE.
