FULL PRODUCT VERSION :
java version "1.4.2-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]


A DESCRIPTION OF THE PROBLEM :
Using JTextPane's insertIcon(...) method when the instance of JTextPane on which the method is being invoked has earlier had setEditable(false) invoked, results in no icon being inserted.
One is still able to insert an icon via a Style and insertString on the JTextPane instance's document though -- so at the very least there's an inconsistency, and more likely this is a bug with insertIcon.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
i.Compile the class included in the source code below
ii. run
iii. click the "insert icons" button - note behaviour
iv. turn off editable via the check box;
v. click "insert icons" again; note behaviour

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
both icons should be inserted whether the text pane is editable or not.
ACTUAL -
both icons were inserted when editable was true, but not when false.


REPRODUCIBILITY :
This bug can be reproduced always.

/**
 * Class demonstrates functionality broken under osX 1.4.1_01 -- that
 * inserting an icon either via JTextPane's insertIcon() or sneaking
 * it in through a style on the text pane's document's insertString
 * doesn't work if the text pane is not editable.<br>
 *
 * This function is also partially broken under Windows 1.4.2_beta --
 * insertIcon() doesn't work if the instance is not editable.
