This seems to be a regression in the 4.6 Neon release. In Mars it used to work, AFAIK. The JDT java editor ignores the set print margin. Instead it shows the print margin at an arbitrary column (120?). Admittedly, in the preferences there is a new description text "Some editors may not honor all of these settings", but * that's not really the point of settings * it used to work in 4.5 * shouldn't all Eclipse UI editors share a common codebase for common stuff like this?
I have observed this too. The text editor print margin has been respected by the Java editor for as long as I can remember, and I've used Eclipse since before 1.0. This is absolutely a regression since Mars. If the Java editor no longer supports the print margin preference it should no long render a print margin. The print margin in the Java editor is indeed permanently set at column 120.
>> Instead it shows the print margin at an arbitrary column (120?) Hi, I did a little research, and found out that: It is not an arbitrary column, it is the setting from your java source code formatter. From menu [Window]-->[Preferences], select [Java]-->[Code Style]-->[Formatter], and then edit your formatter profile. In the tab page [Line wrapping], you can find a setting named "Maximum line width". Change this setting, and the print margin in Java source editor will be changed too. So, looks like it is not a regression. Java source editor is using the "Maximum line width" setting from the java source code formatter profile setting, instead of the common print margin setting.
