M3UA DUPU packets processing, misread parameters User and Cause

[vasilileliuh]

Is this a BUG REPORT or FEATURE REQUEST?:

kind bug

What happened:

During reading DUPU packets in UserCauseImpl class (org.restcomm.protocols.ss7.m3ua.impl.parameter) a first variable "user" receive value of field "Unavailability cause" (by RFC 4666, chapter 3.4.5, p. 43) and second variable "cause" receive value of field "User Identity". In result we have user = 1 and cause = 5 but it should be vice-versa and NullPointerExaption in
org.mobicents.protocols.ss7.mtp.Mtp3UserPartBaseImpl$MsgSystemDeliveryHandler.run(Mtp3UserPartBaseImpl.java:347)

What you expected to happen:

Variable "user" should read data of field User Identity of DUPU packet
and "cause" should read data of field Unavailability cause

How to reproduce it (as minimally and precisely as possible):

Looks like a human error from the initial 7 projects.

Anything else we need to know?:
