This bug was found by St.Petersburg Java SQE team (by Sergey Scherbakov).

  The javax.swing.JEditorPane c-tor throws NullPointerException
 if mime type of the content is wrong.

The javadoc says:
public JEditorPane(String type,
                   String text)

    Creates a JEditorPane that has been initialized to the given text.
    This is a convenience constructor that
    calls the setContentType and setText methods.
    Parameters:
       type - mime type of the given text.
       text - the text to initialize with.

public final void setContentType(String type)

    Sets the type of content that this editor handles. This calls
    getEditorKitForContentType, and then setEditorKit if an editor <--
    kit can be successfully located. This is mostly convenience
    method that can be used as an alternative to calling setEditorKit
    directly.

    If there is a charset definition specified as a parameter of the
    content type specification, it will be used when loading input
    streams using the associated EditorKit.
    ...
    Parameters:
       type - the non-null mime type for the content editing support.



The example:
-------------------------------------------------------------
public class Test {
  public static void main(String[] argv) {
      javax.swing.JEditorPane object =
       new javax.swing.JEditorPane("unknown/unknown", "The text");
   }
}
-------------------------------------------------------------

Output:
java full version "JDK-1.2.2-A"
java -Djava.compiler=NONE Test
