Created attachment 141537 [details] Log file showing NPE at startup On OSX 10.9 Mavericks, if the main monitor is mirrored to another monitor then Netbeans 7.4 reports a NullPointerException at startup while initializing AWT. >Log Session: Thursday, October 24, 2013 2:44:27 PM EDT >System Info: Product Version = NetBeans IDE 7.4 (Build 201310111528) (#6523d6792981) Operating System = Mac OS X version 10.9 running on x86_64 Java; VM; Vendor = 1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08; Oracle Corporation To reproduce: On a Mac with multiple monitors running 10.9, open System Preferences and click on Displays. On the Arrangement tab, check the Mirror Displays option. Launch Netbeans -- it will begin launching but stop before the splash screen appears. Log file attached.
After Netbeans fails to launch, uncheck the Mirror Displays option and try again. This time it launches.
I'm haveing the same problem but I've unchecked mirror displays and Netbeans does not launch still! MacOSX 10.9 Netbeans 7.4 Java Version 7 update 45 I've disconnected the monitors and restarted and nothing still. Tried reinstalling netbeans but there is an error after installation begins writing reading "The Installation Failed" Netbeans Launch bar Icon jumps up one time and then stops and no windows appear as if it never started.
had to install jdk then reinstall netbeans
Cannot reproduce in Product Version: NetBeans IDE 7.4 (Build 201310111528) Java: 1.7.0_45; Java HotSpot(TM) 64-Bit Server VM 24.45-b08 Runtime: Java(TM) SE Runtime Environment 1.7.0_45-b18 System: Mac OS X version 10.9 running on x86_64; UTF-8; en_US (nb) Reporter, what resolution is your external display?
This describes my hardware, but in this configuration only the two smaller monitors are mirrored. The failure only happens when the iMac monitor is mirrored to at least one other. When the failure happens, the main monitor is mirrored to the middle monitor. So the total desktop size is the iMac screen and the HP screen combined.

After further testing I have reproduced this problem without Netbeans, so I am confident it is a problem in the JVM. I reported the problem to Oracle and got a response back saying the bug would be entered into their database with Bug Id: 9007699.
