A few weeks ago Mateusz Matela has been accepted as a GSoC Student to work on toString(). His app looked most promising and I'm convinced he'll complete the term successfully. And in case he stumbles, Mike Haller and I run to the rescue.
toString() generation is pretty basic functionality which is definitely useful to any Java developer. So take a moment and add your ideas to our planned features. Also make sure to check back once coding has started May 26.
Other accepted Eclipse GSoC projects are listed on the wiki. Check 'em out too!
