> Zoom in "preview screen" should cause NullPointerException, because of 
> incorrect use of synchronized in  class 
> org.apache.fop.render.awt.viewer.PreviewPanel. 
> Method PreviewPanel.reload() is synchronized, but it creates new Thread, 
> which is not under synchronized control. Sometimes, when it is later run 
> method PreviewPanel.showPage(), it finishes with NullPointerException (array 
> pagePanels is initialized, but objects in the array not -- see 
> PreviewPanel.ShowPageImage.run statement pagePanels[pg - 
> firstPage].setPage(pg);)
