Description Markus Keller CLA 2014-03-10 15:13:02 EDT 
After bug 429814 is fixed, we should work out what Open Declaration (F3) is supposed to be doing on a lambda expression's "->".

The easy answer is it should jump to the declaration, i.e. to itself (like F3 on a method declaration just selects the method name).

However, that's rarely useful/wanted, and there's a much more useful target:
The implemented functional interface method. I.e. "Open Super Implementation".

This is what happens right now (with bug 429814) on Ctrl+Click. It currently doesn't work on F3 because of bug 429785 (codeSelect doesn't work without selection) and because SelectionConverter#codeResolve(IJavaElement, ITextSelection) now always invokes codeSelect at the *end* of the selection (since bug 75353).

The SelectionConverter#codeResolve methods should at least handle a selection of "->" (length == 2) properly and invoke codeSelect on the given selection. Selections of length 0 should work as expected after bug 429785 is fixed.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
