The following is a part of my code:
-------------------------------------------------------
for (IOrder order: engine.getOrders(instrument)) {
if (order.getComment().equals(COMMENT1)) {
-------------------------------------------------------
It caused NullPointerException at order.getComment().equals(COMMENT1)
after partial fill message.
Is this a bug of JForex?
If not, how can I avoid this error?
Thanks.

This is not JForex bug since comment can be null in order. To avoid this, use construction like :
-------------------------------------------------------
for (IOrder order: engine.getOrders(instrument)) {
if (COMMENT1.equals(order.getComment())) {
-------------------------------------------------------
but only if COMMENT1 is constant or you sure it's not null, otherwise use additional check for null :
if (COMMENT1!=null && COMMENT1.equals(order.getComment()))
