Comment 2 Ondrej Vrabec 2013-06-27 08:58:56 UTC 
the variable was a hashmap containing about 10000 entries btw
Comment 3 Martin Entlicher 2013-07-25 12:25:39 UTC 
The Swing execution is simply slow. IMHO this can not be fixed.
javax.swing.text.BoxView.setSpanOnAxis() takes 25,640 ms
Comment 4 Martin Entlicher 2013-07-25 14:24:00 UTC 
Reopening. I was able to reproduce this with a large HashMap. Like:

        HashMap hm = new HashMap();
        int n = 100000;
        for (int i = 0; i < n; i++) {
            hm.put("i = "+i, i);
        }
        hm.size();

The tooltip on "hm" takes a long time to display.
