Its specifically to address bad user code. For example:
http://issues.apache.org/bugzilla/show_bug.cgi?id=39088
Its the case where ServletException.getCause() returns something an
instance of "user's custom Throwable" .. then the "user's custom
Throwable" returns itself as the root cause.

Adding this to both loops may be helpful too:
if (rootCause == rootCause.getCause()) {
break;
}
Throwable.getCause does return null in that case, so the loop should get
out:
public Throwable getCause() {
return (cause==this ? null : cause);
}
