Hi, searching for something easy and interessting to work on i discovered JDK-8055197 which is maybe a "bug" or "just" a side effect of using RICHEDIT_CLASS instead of EDIT. I think RICHEDIT_CLASS is introduced for TextField because of JDK-7092551. And it "breaks" a strage behavior of the TextField. With the TextField prior to Java7 you can set a text that contains newlines. And you can edit the text (add chars before and after the newline) and you can remove the newline by hitting delete or backspace depending to your actual position of your cursor. While moving the cursor your will find that the cursor pauses (you must press cursor-right or cursor-left two times to jump over the newline) at the newline.
But what ever you do, you cannot insert an new newline. Not by typing. Not by copying. So i would argue that is is a minor discrepancy in the win32 api for TEXT edit-Control. I think we can emulate the old behavior from java6, but before i put greater effort in this, i think we should discuss if JDK-8055197 is a bug or if it is an descrepancy-fix, because TextField is a singleline-control? -- Sebastian
