It does not matter /that/ much to me and I just wanted to record my opinion,
that is all, no biggie.

I still would like to know if JDiff can figure out changes without being
confused by method order changes.

Perhaps, but a veto is still a veto.

Also, given that you're using Eclipse, is really doesn't matter what order
the methods are in, because you can navigate to them so easily anyway.

Hi Stephen,

up and down and - god forbid - think.

Good point WRT deltas b/w versions as far as raw text but would not JDiff
handle such cases?

An arbitrary layout based on the alphabet is unsuitable. A related methods
together is much better. Hashcode should be near Equals. Contains should be
near IndexOf and LastIndexOf..

Also, this change makes it impossible to determine what really changed
between versions. I want 2.0 of lang and 3.0 of collections to represent
that fresh start where they are actively maintained (added to/bug fixes),
rather than actively developed (refactored/added to/bug fixes).
