Description
When using NetBeans on Win platform with JDK 1.6.0_10, NetBeans users reported they got
following NPE from time to time:
Stacktrace:
java.lang.NullPointerException
at com.sun.java.swing.plaf.windows.WindowsComboBoxUI$XPComboBoxButton.getState(WindowsComboBoxUI.java:408)
at com.sun.java.swing.plaf.windows.XPStyle$GlyphButton.paintComponent(XPStyle.java:717)
at javax.swing.JComponent.paint(JComponent.java:1027)
at javax.swing.JComponent.paintChildren(JComponent.java:864)
at javax.swing.JComponent.paint(JComponent.java:1036)
at javax.swing.JComponent.paintChildren(JComponent.java:864)
Unfortunately, issue is random so I can't give you fully reproducible steps. But by looking at NetBeans exception reporter results: http://statistics.netbeans.org/analytics/detail.do?id=11541 we can see that issue is relatively frequent for NetBeans users (already 20 duplicates)
Just suggestion - maybe blind null check would be enough to fix this issue?
I forgot to mention exact JDK build for exception, here it comes:
VM: Java HotSpot(TM) Client VM, 11.0-b11, Java(TM) SE Runtime Environment, 1.6.0_10-beta-b20
OS: Windows XP, 5.1, x86
