A DESCRIPTION OF THE REQUEST :
The current java release (1.4.1_02) HTML support has never changed since its original release in j2se 1.2.

Packages javax.swing.text.html and javax.swing.text.html.parser are both using the old and deprecated HTML 3.2 specification.

Many applications need HTML support, for input, output or rendering, so upgrading this packages to stay current with the standard its a must.



JUSTIFICATION :
quoting the W3c.org specification
http://www.w3.org/TR/html401/

This specification defines HTML 4.01, which is a subversion of HTML 4. In addition to the text, multimedia, and hyperlink features of the previous versions of HTML (HTML 3.2 [HTML32] and HTML 2.0 [RFC1866]), HTML 4 supports more multimedia options, scripting languages, style sheets, better printing facilities, and documents that are more accessible to users with disabilities. HTML 4 also takes great strides towards the internationalization of documents, with the goal of making the Web truly World Wide.
[...]
W3C recommends that user agents and authors (and in particular, authoring tools) produce HTML 4.01 documents rather than HTML 4.0 documents. W3C recommends that authors produce HTML 4 documents instead of HTML 3.2 documents. For reasons of backward compatibility, W3C also recommends that tools interpreting HTML 4 continue to support HTML 3.2 and HTML 2.0 as well.

EXPECTED VERSUS ACTUAL BEHAVIOR :
A rendering engine which displays well formed HTML4.01 documents
