i've been using a tricky way doing auto-scroll for JTextPane. hope this work for you too.

the idea is to enforce the viewport scroll to the last line of the by selecting the last character of the text. here is the code:


JTextPane pane = new JTextPane();
... // add some text to the JTextPane
...
Document doc = pane.getDocument();
pane.select(doc.getLength(), doc.getLength()); // this should enforce the viewport move to where the line being selected.
...

i've been using it to display process log. so, you can try about it.
have fun.
