[VTN-46] PathMap class handles mapIndex field incorrectly.

Thu, 3 May 2018 15:45:10 +0000

mapIndex field in PathMap class keeps an Integer instance which represents
the path map index. But some methods treat it as int value incorrectly.

equals(Object) compares mapIndex values using == operator.
Naturally mapIndex values need to be compared using equals(Object).
hashCode() dereferences mapIndex field without null check.
So it causes NPE if mapIndex is null.
