FlowView.layout causes ArrayIndexOutOfBoundsException

FULL PRODUCT VERSION :
java version "1.6.0-beta2"
Java(TM) SE Runtime Environment (build 1.6.0-beta2-b86)
Java HotSpot(TM) Client VM (build 1.6.0-beta2-b86, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
This code in FlowView.FlowStrategy.layout is problematic as it's written in JDK 1.6:

                rowIndex = fv.getViewIndexAtPosition(damageStart);
                if (rowIndex > 0) {
                    rowIndex--;
                }
                p0 = fv.getView(rowIndex).getStartOffset();

Since fv.getViewIndexAtPosition can return -1, the later fv.getView(rowIndex) can (and often does) throw ArrayIndexOutOfBoundsException.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
This is easily generated on my machine using a JEditorPane in HTML mode with editable = true and an embedded image. Just select some nearby text and it happens. I haven't done the work to extract that code into a simple runnable, but since the fix would be so easy hopefully this won't be necessary.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
In JDK 1.5 there are no exceptions.
ACTUAL -
An exception is thrown, then nothing in the box is rendered until something triggers a clean redraw.

REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
Since everything in the stack trace is Sun/Swing code, I could find no easy work-around. The only practical workaround is to not use JDK 1.6.
