A DESCRIPTION OF THE PROBLEM :
BasicOptionPaneUI.addMessageComponents() uses recursion to split message strings at newlines, generating a StackOverflowError when the message string contains an unusually large number of newlines (approximately 5000+).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
scrappy:Documents jimdouglas$ cat OptionPane.java
public class OptionPane
{
    public static void main(String[] argv) throws Exception
    {
        String message = java.nio.CharBuffer.allocate(5000).toString().replace('\0','\n');
        javax.swing.JOptionPane.showMessageDialog(null, message);
    }
}
