If the offset is beyond the end of a DefaultStyledDocument in a call to
setCharacterAttributes() , the method consumes all available memory, and
eventually throws OutOfMemoryError.

Sample code:

import javax.swing.text.StyledDocument;
import javax.swing.text.DefaultStyledDocument;
import javax.swing.text.SimpleAttributeSet;

/** A simple class to test what happens if I try to set character
 * attributes beyond the end of the StyledDocument. Ideally, there would
 * be some sort of exception. In fact, what happens is an
 * ever-increasing use of memory until it runs out. */

public class bugtest {
  public static void main(String args[]) {
    StyledDocument sd = new DefaultStyledDocument();
    SimpleAttributeSet attrib = new SimpleAttributeSet();
    sd.setCharacterAttributes(2, 2, attrib, false);
    System.out.println("Success - no bug");
  }
}

run with java -verbose:gc bugtest to see the result quicker.
