Hi, I think it is impossible to implement something like this in "transparent" way. You can disable verifier, but I do not think it is good solution. Class scaning will not solve this problem :
Date now = new java.util.Date() ; // calls System.currentTimeMillis(); I use Date now = MyDateUtils.now(); to implement things like this, I think it is the best solution if you are going to test *your* application. > AFAIK, it is not possible to modify core Java classes > (not without cheating anyway). > > You can, however, modify all other classes.
