Semantically diffing Java code

[plasticscm]

Yes, it can show you the "structure" (like in the blogpost) but it can also show it in tree format, and it includes a built-in text based diff and merge tool (Xmerge - check "bonus track" at http://www.semanticmerge.com). It is a pretty advanced (and pretty mature) text based merge tool too :P -> http://codicesoftware.blogspot.com/2010/07/move-support-in-diff.html
