FULL PRODUCT VERSION :
java version "1.4.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
Java HotSpot(TM) Client VM (build 1.4.0-rc-b91, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]


A DESCRIPTION OF THE PROBLEM :
Using the JEditorPane in "edit" mode for HTML documents and
entering a hard-break (a <br> tag) does not move the cursor
as expected.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the example:
   javac BRHTMLEditorKit.java
2. Start the example:
   java BRHTMLEditorKit
3. Type some text, then hit the SHIFT-ENTER key.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I would Expect the cursor to move to the next line just as
when hitting the ENTER key.

The cursor remains on the first line and a gap is added
between the (hidden) BR element and the cursor. When typing
another character, the cursor moves to the next line as
expected.

This bug can be reproduced always.
