DO NOT REPLY [Bug 44936] New: NullPointerException in JSVGScrollPane

https://issues.apache.org/bugzilla/show_bug.cgi?id=44936

           Summary: NullPointerException in JSVGScrollPane
           Product: Batik
           Version: 1.7
          Platform: PC
        OS/Version: Windows Vista
            Status: NEW
          Severity: critical
          Priority: P1
         Component: GVT
        AssignedTo: batik-dev@xmlgraphics.apache.org
        ReportedBy: scorefande@yahoo.de


Occasionally there's a NullPointerException thrown in the JSVGScrollPane.

It usually occurs when I quickly move the cursor over several elements that
have tooltips and change their color with the set attribute. Then the whole
SVGCanvas is white and is only repainted when I move the mouse over alle the
displayed elements or resize the JInternaFrame that contains the canvas.

This happens because the viewBox is sometimes null.

The Exception occurs in updateCompleted(UpdateManagerEvent e) method of the
ScrollListener.

Rectangle2D newview = getViewBoxRect();

The newview variable is null.
