I remember having a similar issue using Cocoa/Java, I think I was
overshooting the text, what happens if you do the same thing but with
textView.textStorage().length() - 1
Cheers

The API says
public NSRange(int location, int length)
As I want to scroll to the last character and select no text at all I
assume calling
scrollRangeToVisible(new NSRange(textView.textStorage().length(), 0))
is correct. No?

Hi cocoa devs,
I experience random crashes with the following code snippet
public void log(String message) {
this.textView.textStorage().replaceCharactersInRange(new
NSRange(textView.textStorage().length(), 0), message + "\n"); //
@warning very bad performance
this.textView.setFont(NSFont.userFixedPitchFontOfSize(9.0f));
this.textView.scrollRangeToVisible(new
NSRange(textView.textStorage().length(), 0));
}
The stack trace usually looks similar to this one

Maybe I'm missing something as I don't use Java but aren't the
parameters you are passing to the NSRange constructors backwards,
i.e. shouldn't they be:
new NSRange(0, textView.textStorage().length())
