1. Run IDE 2. Open some window e.g. Main menu Window -> Files 3. Drag the header of opened window to some other area 4. Ghost Image should appear, but that doesn't happened Product Version: NetBeans IDE Dev (Build 201102240001) Java: 1.7.0-ea; Java HotSpot(TM) Client VM 21.0-b02 System: Linux version 2.6.32-28-generic running on i386; UTF-8; en_US (nb) Note: In jdk1.6.0_24 works fine.
Not a stopper for 7.0.1, but clearly this is a regression in comparison to running NB on JDK 6 (tested the build 20110608 & JDK7b145)
i don't think this is fixable in netbeans. we use JNA library to access some native os features so it's either a bug in JDK 7 or we need to update JNA library (or both)
it seems the layout of binary files in JDK 7 distribution has changed on linux as i'm getting the following exception from JNA lib: INFO [org.netbeans.core.windows.view.dnd.DragAndDropFeedbackVisualizer] java.lang.UnsatisfiedLinkError: libjawt.so: cannot open shared object file: No such file or directory at com.sun.jna.Native.getWindowHandle0(Native Method) at com.sun.jna.Native.getComponentID(Native.java:277) at com.sun.jna.platform.WindowUtils$X11WindowUtils.getDrawable(WindowUtils.java:1296) at com.sun.jna.platform.WindowUtils$X11WindowUtils.access$800(WindowUtils.java:1117) at com.sun.jna.platform.WindowUtils$X11WindowUtils$2.run(WindowUtils.java:1316) at com.sun.jna.platform.WindowUtils$NativeWindowUtils$2.hierarchyChanged(WindowUtils.java:365) at java.awt.AWTEventMulticaster.hierarchyChanged(AWTEventMulticaster.java:498) at java.awt.Component.processHierarchyEvent(Component.java:6671) even the latest version of JNA library doesn't handle this.
.. so we need to at least file issue against JNA and add the issue number here.
Doesn't work either in actual versions of NB, JDK and JNA library. Product Version: NetBeans IDE Dev (Build 201206070001) Java: 1.7.0_04; Java HotSpot(TM) Client VM 23.0-b21 System: Linux version 3.0.0-20-generic running on i386; UTF-8; en_US (nb) JNA version 3.4.0 In JDK 6 still works fine.
