This issue appeared after fixing JCK-7301914 (which itself appeared due to the spec update in JDK-7016396)

The spec
http://docs.oracle.com/javase/8/docs/api/javax/swing/text/View.html#getNextVisualPositionFrom-int-javax.swing.text.Position.Bias-java.awt.Shape-int-javax.swing.text.Position.Bias:A-
says:

"BadLocationException - the given position is not a valid position within the document"

However for positions larger than the siaze of the document BLE is not thrown.

Please consider the following code:

--------------------------------------------------------------
package temp;

import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;

public class BLE {
    public static void main(String[] args) throws BadLocationException {
        SwingUtilities.invokeLater(() -> {
            JFormattedTextField jtf = new JFormattedTextField();
            NavigationFilter nf = new NavigationFilter();
            jtf.setText("Test for Tests");
            JFrame jf = new JFrame();
            jf.getContentPane().add(jtf);
            jf.pack();
            jf.setVisible(true);
            Graphics g = jf.getGraphics();
            jf.paint(g);
            Position.Bias[] biasRet = {Position.Bias.Forward};
            try {
                nf.getNextVisualPositionFrom(jtf, 500, Position.Bias.Backward, SwingConstants.EAST,biasRet);
                nf.getNextVisualPositionFrom(jtf, Integer.MAX_VALUE, Position.Bias.Forward, SwingConstants.EAST,biasRet);
            } catch (BadLocationException e) {
                e.printStackTrace();
            }
        });
    }
}
--------------------------------------------------------------

No BadLocationException is thrown.

In addition to this there is a problem with the spec for the following method
http://docs.oracle.com/javase/8/docs/api/javax/swing/text/NavigationFilter.html#getNextVisualPositionFrom-javax.swing.text.JTextComponent-int-javax.swing.text.Position.Bias-int-javax.swing.text.Position.Bias:A-


BadLocationException is present but not described.

The following test fails due to this problem
