19 Feb 2000, eval1127@eng -- at user's request, am filing a new, separate bug for this issue. While (I thought it was) similar
to bug # 4312959, user strongly believes otherwise. User also notes that this is a NEW issue for kestrel.

[ 18 Feb 2000, eval1127@eng -- this looks like another aspect of the same problem reported earlier by same user (# 4312959).
In this example, having a smaller initial enclosing frame increases the odds of the overlaying/squashing behavior appearing. ]

C:\javaBugs\JDK1.3_RC1_HTMLDisplayProblems_2>java -version
java version "1.3.0rc1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0rc1-T)
Java HotSpot(TM) Client VM (build 1.3.0rc1-S, mixed mode)

Using JDK 1.3 RC1, some HTML pages are garbled on display, but not all the time!
The same page may display OK some times and then at other times much of the
page is compressed into blobs of overlayed characters in a column on the far
left side of the page.

The same pages display fine when using JDK 1.2.2.

  To reproduce the problem compile and run the following program.

% javac TestHTMLRead.java
% java TestHTMLRead

TestHTMLRead.java:
public class TestHTMLRead extends javax.swing.JFrame
    implements java.awt.event.ActionListener
{
// Using JDK1.3 RC1 some HTML pages are garbled when displayed with a
JEditorPane, but not all
// the time! If the page displays correctly DON'T GIUE UP THIS IS A NASTY
UNSIGHTLY BUG, try
// pressing reload again. If it still works, try rerunning the program. I find
that the
// program usually works the first time, but fails if I exit and rerun! It
appears to be
// timing dependent. Try clicking the reload button sooner after running the
program.
//
// The URL given is one of several pages I have seen this problem on, this one
seems to be
// more consistent than the others. Sometimes after it has failed, I can
enlarge the
// window, and reload with the result of the table being displayed correctly,
but
// with HTML text still at the bottom.
//
// This test program demonstrates two problems:
//
// 1) The layout of the table on the page is garbled.
//
// 2) Some of the HTML text is being displayed at the bottom of the page.
//
// Running the same program with JDK 1.2.2 there are no problems.
//
