The docs for the methods in java.awt.font.TextMeasurer do not mention the
Exceptions that should be thrown, nor do they all throw the same Exception.
insertChar(AttributedCharacterIterator newParagraph, in insertPos) &
deleteChar(AttributedCharacterIterator newParagraph, in deletePos) throws an
ArrayIndexOutOfBoundsException for all values of insert/deletePos not in
bounds.
getAdvanceBetween(int start, int limit) , getLayout(int start, int limit) &
getLineBreakIndex(int start, int advance) throw IllegalArgumentException for
all values of start, limit and advance not in bounds.


Sample code follows....

import java.awt.font.TextMeasurer;
import java.awt.font.TextLayout;
import java.text.AttributedString;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;
import java.text.AttributedCharacterIterator;
import java.text.BreakIterator;

public class test {
public test() {
        String string = "01234567890123456789";
        AttributedCharacterIterator text = (new AttributedString(string)).
            getIterator();
        FontRenderContext frc = new FontRenderContext(new AffineTransform(),
            true, true);
        TextMeasurer measurer = new TextMeasurer(text, frc);

  try {
   measurer.getAdvanceBetween(-1,20);
  }
  catch (Exception exc) {
   System.out.println(exc);
  }

  try {
   String newstring = "0134567890123456789";
   AttributedCharacterIterator newtext = (new AttributedString(newstring)).
    getIterator();
   measurer.insertChar(newtext,-1);
  }
  catch (Exception exc) {
   System.out.println(exc);
  }

  try {
   String newstring = "0134567890123456789";
   AttributedCharacterIterator newtext = (new AttributedString(newstring)).
    getIterator();
   measurer.deleteChar(newtext,-1);
  }
  catch (Exception exc) {
   System.out.println(exc);
  }

}

    public static void main(String[] args) {
       new test();
    }
}
