FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
FULL OPERATING SYSTEM VERSION :
Windows Millennium [Version 4.90.3000]
ADDITIONAL OPERATING SYSTEMS :
A DESCRIPTION OF THE PROBLEM :
When editing the content of a JEditorPane with content type
set to "text/html", a BadLocationException can be thrown
when attempting to delete all text. Seems to occur only if
the text to be deleted has been wrapped and has been
selected with Ctrl-A.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
(See source code below.)
Set the content type to "text/html" in a JEditorPane, then
setText() to a string that gets wrapped when displayed.
If you then perform the following sequence to delete the
text in the JEditorPane:
1. Click on the JEditorPane
2. Press Ctrl-A to select all
3. Press Delete
a BadLocationException is thrown.
