Its a "feature" of the forums.
Read the [url http://forum.java.sun.com/faq.jsp#format]special tokens link on the posting page.
To get around the problem, when posting code to the forums don't use [i] as an array index (I use [j] instead). Many users of these forums have asked several times for this to be changed, but to no avail; so we just have to live with it.
