C:\javaBugs\JDK1.3_RC3_CSS_stringToColor.StringIndexOutOfBounds>java -version
java version "1.3.0rc3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc3-Z)
Java HotSpot(TM) Client VM (build 1.3.0rc3-Z, mixed mode)

JEditor.setPage(url) where url is a page containing BGCOLOR="" results in a
StringIndexOutOfBoundsException: String index out of range: 0 within
String.chartAt called from
javax.swing.text.html.CSS.stringToColor(CSS.java:818). This is followed by a
NullPointerException in
javax.swing.text.ParagraphView.getLayoutViewCount(ParagraphView.java:97).

Source of Test Program:

public class TestHTMLRead extends javax.swing.JFrame
    implements java.awt.event.ActionListener
{
// Using JDK1.3 RC3, the display of an HTML page with BGCOLOR="", such as
// all of those in www.partsBase.com/xxx, will result in a
// StringIndexOutOfBoundsException. To replicate the bug, start this
// program which displays a window with a JEditorPane and then press the
// "reload" button at the buttom of the screen, which will set the page
// of the JEditorPane to a page with BGCOLOR="" to get the Exception.
//

// String url = "http://www.partsBase.com/auction";
    String url = "http://www.partsBase.com/parts";
