Examples of javax.swing.text.BadLocationException

javax.swing.text.BadLocationException
This exception is to report bad locations within a document model (that is, attempts to reference a location that doesn't exist).
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}. @author Timothy Prinzing
