FULL PRODUCT VERSION :
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)

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

A DESCRIPTION OF THE PROBLEM :
// t is a TextArea
t.replaceRange("",t.getSelectionStart(),t.getSelectionEnd());
This code use to work as a "cut" function with JDK1.4.1 and earlier.
Ever since JDK1.4.2 (and 1.5 beta) this does not work properly.
The wrong text is cut.
This happens if you cut in any line other than the first line.
It seems to have something to do with endline chars.
The cut position is out by 2*(lineNo).
Either replace range method is broken, or getSelectionStart and getSelectionEnd use incorrect location values.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the sample code.
Resize the frame so that it is big enough.
Enter the following text
000
111
222
333
444
Hilight the row no1 row i.e. "222"
click the button.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The row with "222" in it SHOULD be removed
ACTUAL -
The row with "333" disappears

REPRODUCIBILITY :
This bug can be reproduced always.
