How would that help? I have been working with java for years and I have
file many a bug report and I can tell you that this is a waste of time.
Sun ignores bug reports. It is just a fact of life. If you do not
believe me just check out these bug reports that I filed last year
(4156278 and 4186776). These are real bugs but they have been ignored.
