I changed the implementation of these methods (findMethod, findConstructor and findField) and see good enough performance improvements | Carlo and me have been playing with various combinations of class hierarchy and number of methods. The existing implementation in ReflectionUtils (i.e. call to getDeclaredMethods()) performs better when the classes are hierarchical and the numbers of methods in this hierarchy is less. However, if the number of methods starts increasing or if there is no/less hierarchy involved in the classes, then the proposed change performs better. So its really a question of which is the right scenario. As for the rest of the changes/questions mentioned in my previous post, they still hold good.
