If I understand you, you can do this.  Exceptions and cl***** are very 
similar so you can say, "public class Mine extends IOException {}" and 
write a new constructor.  You still have to change the code to use your 
new exceptions.

So my second suggestion would be to add the logging code to the runtime 
library and whip up a special rt.jar file.
