Alexey A. Ivanov updated HARMONY-1809:
--------------------------------------

    Attachment: HTest1809.java

This is test which demonstrates weird behaviour of GapContent.replace.

------- RI output (BEA JRockit 1.5) -------
text: 'xt

start = -2, end =5

------- Harmony output (where replace merely swallows BLE; as proposed in HARMONY-1975) -------
text: 'text
'
start = 4, end =9
after insert: 'Stext
'
===============


As for Harmony it doesn't modifies the contents in both cases, and the GapContent object remains usable. At the same time RI, performs replace updating content but the object becomes unusable.
