(this is just an InlineCssTextArea)
In the picture, lines 4 and 5 have no content (other than a standard \r\n)

if I put my cursor on line 4 than drag it to line 5, I get the following exception

(I should also mention copy and pasting stuff from the text area adds an extra \n to everything)
Heres the IndexRange code
public IndexRange(@NamedArg("start") int start, @NamedArg("end") int end) {
if (end < start) {
throw new IllegalArgumentException();
}
this.start = start;
this.end = end;
}
apparently RichText is getting confused about where a \n fits in selection.
This error also happens with various other selections regarding lines of whitespace and also renders the code area unusuable after error.
Using richtextfx-fat-0.6.4.jar
