Jan Lahoda commented on NETBEANS-1440:
--------------------------------------
So, to reproduce:
# let the very last line in the editor is empty
# have the editor caret at the very last line
# have the mouse cursor over the last line as well
# double click, but don't release on the second click (i.e. down-up-down)
# move the mouse to right
Seems the issue is that the caret is moved beyond the document end (the
document content always contains as extra invisible character at the very end)
in EditorCaret.mouseDragged. So far, seems LineDocumentUtils.getWordEnd needs
fixing.
