IDE log

I had just done "Run" on a Node.js/HTML5 application (but I'm not sure if that's the cause), when NetBeans gave me the dialog to review and report an exception. The dialog only contained "java.lang.ArrayIndexOutOfBoundsException" & no matter what I did, the dialog kept coming back.

Comment 1 terje7601 2015-07-16 06:46:22 UTC 
Note: I also upgraded to Java 8u51 yesterday, so maybe it's actually a regression in Java (just guessing).

The root cause (I think) is in the IDE log at line 1342:

java.lang.ArrayIndexOutOfBoundsException: 3 > 2
	at java.util.Vector.insertElementAt(Vector.java:598)
	at javax.swing.plaf.basic.BasicTabbedPaneUI$Handler.updateHtmlViews(BasicTabbedPaneUI.java:3593)
	at javax.swing.plaf.basic.BasicTabbedPaneUI$Handler.componentAdded(BasicTabbedPaneUI.java:3718)
	[...]

Comment 3 Martin Entlicher 2015-09-11 16:49:47 UTC 
I do not think this is a regression, we have already issue #252635 with the report of an ArrayIndexOutOfBoundsException without a corresponding stack trace.

It is likely associated with the ArrayIndexOutOfBoundsException: 3 > 2
	at java.util.Vector.insertElementAt(Vector.java:598)
	at javax.swing.plaf.basic.BasicTabbedPaneUI$Handler.updateHtmlViews(BasicTabbedPaneUI.java:3593)
	at javax.swing.plaf.basic.BasicTabbedPaneUI$Handler.componentAdded(BasicTabbedPaneUI.java:3718)

and ArrayIndexOutOfBoundsException: 3 >= 2
	at java.util.Vector.elementAt(Vector.java:474)
	at javax.swing.plaf.basic.BasicTabbedPaneUI.getTextViewForTab(BasicTabbedPaneUI.java:1706)
	at javax.swing.plaf.basic.BasicTabbedPaneUI.calculateTabHeight(BasicTabbedPaneUI.java:1717)
	at javax.swing.plaf.basic.BasicTabbedPaneUI.calculateMaxTabHeight(BasicTabbedPaneUI.java:1742)

This can occur if the UI objects are accessed outside of AWT event queue. But it's hard to find out if this is really the case and if so, where it is.
Comment 4 Martin Entlicher 2015-09-11 16:54:56 UTC 
Is the exception reproducible, does it still happen to you?

It's not reproducible, and I haven't had this exception since I reported it.
