That have a place to use this class, you don't change it, or you change it didn't compile, or use of this class code in the jars, or use the code for this class may be correct, but you rely on the old version of this code, along with a variety of possibility, in the final analysis, is before you have a place to use class code is invoked, find the call is fairly simple, exception stack push one layer, basic is the first class of your own system
