Description ebakke 2013-11-04 00:12:01 UTC
This is probably a MacOS-specific bug. It's easy to reproduce; just open up a source editor window and press Meta+EQUALS to zoom the text in. The text is rapidly zoomed in two steps instead of one (zoom back out again with Meta+MINUS, and you'll see that you're not back to the previous zoom factor like you would otherwise).

The problem is related to the Meta+EQUALS key combination, not to the Zoom Text In action. Any action assigned to this keyboard shortcut will have the same behavior (e.g. the "Start New Line" action will insert two lines instead of one if invoked via this keyboard shortcut). I've also confirmed the same behavior in my own NetBeans Platform application.

There was a related bug with the DELETE key on MacOS a while back [1], but its underlying JDK bug was fixed [2], backported to 7u40 [3], and closed, and I can no longer reproduce that particular bug (I'm running 1.7.0_45-b18). Hence I'm filing a new bug.

It is reproducible with JDK7, but I tried it with JDK8 b115 and it seems to be fixed. Can you please verify that? You can download latest JDK8 at

I'll close the issue as wontfix since it is most likely fixed JDK bug, but feel free to reopen it if you think otherwise.

I can confirm that the bug seems to be fixed on 1.8.0-ea; Java HotSpot(TM) 64-Bit Server VM 25.0-b59--it makes sense to close it. Thanks!
