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 :
Windows 98 [Version 4.10.2222]




A DESCRIPTION OF THE PROBLEM :
The JTextPane insertIcon method doesn't insert the image if
the JTextPane contains an HTML document. Instead of
inserting the image, it inserts a couple inch gap at the
insertion point. In contrast, the insertIcon method works
fine for either regular StyledDocument or RTF documents.

This is an improvement on the situation for 1.3.1, 1.3, and
1.2.2. Under those versions the same code throws:
java.lang.ArrayIndexOutOfBoundsException: -1 < 0

This was first reported as bug report 4240377 for the Swing
classes under JDK 1.1. The bug was closed as "not
reproducible". Three subsequent posting under that bug
report thread indicated that it was still a bug in 1.2.2 and
1.3.1, but it does not appear the bug was ever reopened.

The code provided below will generate the
ArrayIndexOutOfBoundsException on 1.2.2, 1.3, and 1.3.1 and
is completely reproducible. The same code under 1.4rc no
longer blows up but it still doesn't insert the image. The
code includes a one line change to switch from an HTML
document to a regular StyledDocument which works fine.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the code below
2. Make sure you have a live network connection since it
fetches the image from the Java web site. Problem still
occurs if you use a local image file:
   new IconImage("image.gif");
3. Replace the "doesn't work" line with the "does work" line
to verify that it works when the document isn't HTML

EXPECTED VERSUS ACTUAL BEHAVIOR :
1.4rc1: a couple inch gap inserted at the insertion point
(which appears to be one character not multiple spaces)

1.3.1, 1.3, 1.2.2:
java.lang.ArrayIndexOutOfBoundsException: -1 < 0


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Here is the stack trace under 1.3.1 (1.3 and 1.2.2 are similar):
