that does not explain why our example is not running in IDE tools such as Eclipse. That's because automatic compilation in the IDE doesn't reproduce the problem, and if you modify the constant class, the IDE tool automatically compiles all the reference classes, "smart" masks the problem, but the potential risk is still there, and I remember that Eclipse should have a portal set up for automatic compilation. You are interested to try it yourself.　Note: The use of class file substitution is proh
