In 4.0 this worked fine, but in current trunk the behaviour of enter is just
silly. Imagine following code and cursor at |: 

public final class Board {
    private Board (int x1, int y1, int x2, int y2) {
        players = new Player[] {
            new Player (x1, y1),|

then pressing enter places me:
            new Player (x1, y1),
                    |

while the natural (and original behaviour of previous version) was:
            new Player (x1, y1),
            |

I consider this a regression which hugely slows down the way I can type text in
our editor.
