The ChangeLog for 0.1.0 says:
Different icon for new() in Outline (Feature Request 850033)
For me, there is no different icon for new(). Does that only work for Eclipse 2.1.x? I use 3.0M7...
Using M8 I do notice some new shiny icons ... or at least what appear to be new icons. I cant really say which icon the changelog was referring to though ...
