BTW, the doc suggests that you start with signing the CLA before forking and raising pull request. In case of individual contribution this is easy and fast, but for corporate route (which I am guessing you have to go through) it can be a long and unexciting part of contribution process.
Likewise, getting your changes to be reviewed can also take time, depending on how big and complex your change is, and how many people are familiar enough with that part of code.
So I suggest that you raise the PR as early in the process as possible, and the CLA bit can catch up (while it's still obviously required before your contribution can be finally accepted)

Thanks for taking time to dive into the issue and deciding to contribute.
I have found the root cause for this issue and also have the fix for the same.
Please guide me if I can contribute for this project as I'm new to this community.

I have noticed a corruption in index after reindexing vertex-centric indices with direction 'IN'.
Issue : A self-link is getting added to every vertex after reindexing.
To demonstrate this, I have taken a very small graph consists of two vertices (A & B) and one edge connecting the two.
Edge Label -> link
Edge has one property key (Integer) -> assocKind
//Creating the Vertex Centrix Index
gremlin > edgeLabel = mgmt.getEdgeLabel("link");
gremlin > assocKind= mgmt.getPropertyKey("assocKind")
gremlin > mgmt.buildEdgeIndex(edgeLabel, "myVertexCentricIndex", Direction.IN, assocKind);
Please note i have given the direction IN for the index.
//Creating the Edge from A to B: (a and b are vertices)
Output Before Reindexing :
gremlin> g.V().has('name' , 'A').inE().hasLabel('link').has('assocKind',1)
//no IN edges to vertex A Correct
gremlin> g.V().has('name' , 'A').outE().hasLabel('link').has('assocKind',1)
Now I ran the reindex command
// 'index' is the vertex centric index which is created above
gremlin> m.updateIndex(index, SchemaAction.REINDEX).get()
Output After Reindexing :
==>e[4e1f-b6g-1bit-b6g][14488-link->14488] Unexpected Link
This issue happens in janusgraph 0.5.2 also.
