FULL PRODUCT VERSION :
Java Plugin 1.4.2_03

ADDITIONAL OS VERSION INFORMATION :
ver Windows XP Professional 2002 Service Pack 1

A DESCRIPTION OF THE PROBLEM :
In an AWT TextArea, after you entered a few newlines, the newlines seem to be counted as positions, causing the replaceRange() function to fail.

The function does something though, but it uses the wrong getSelectionStart() and getSelectionEnd(). These are shifted as many positions as what seems to be the number of returns entered.

My textArea applet works fine in earlier plugins, so I think it is a bug.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
   public void vervang(String bgn, String nd) {
    undo_bgn = bgn;
    undo_nd = nd;
    werkTekst = tekst.getSelectedText();
    rplcTekst = bgn + werkTekst + nd;
    tekstBegin = tekst.getSelectionStart();
    tekstEind = tekst.getSelectionEnd();
    tekst.replaceRange(rplcTekst, tekstBegin, tekstEind);
    tekst.requestFocus();
    done = true;

  }

The above function takes to arguments that are to be put before and after a selected text in the textarea. The selected text will be replaced by the sum of arg1, selectedText, arg2.

The function vervang(arg1, arg2) is called from javascript:
vervang("starttext","endtext");



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You should just be able to replace a selected text with any other text.
ACTUAL -
The new text is pasted in the text you were editing, somewhere past the originally selected text, overwriting a piece of text and leaving the originally selected text as is.

REPRODUCIBILITY :
This bug can be reproduced always.
