[Bug swing/26590] New: NPE in WrappedPlainView.updateMetrics

[thebohemian at gmx dot net]

When I treat a JTextArea like this:
ta = new JTextArea();
ta.setLineBreak(true);
ta.setWrapStyleWord(true);

and try to display it the following exception will occur:

java.lang.NullPointerException

This will happen in the Swing example application as it contains JTextAreas in
that configuration.
