Henri Yandell commented on LANG-784:
------------------------------------
I'm in favour of javadoc improvement. Something that notes that 'This means
that "abc" - "ab" is the empty String, not "c".' If we'd been redoing it, I'd
probably make it work the other way. Show the remainder of the first String and
not the second String, but we're API bound now.
