The result looks odd because your data is improperly configured, GS before
version 2.1 did not notice, but 2.1 does.
The issue is that you declared EPSG:4326 as the reference system with a
dataset that is clearly not in that SRS, since you have coordinates in
the ranges of millions.
The current implementation is looking at the request and replicating
the polygons many times over the requested area to perform map wrapping:

The proper EPSG code for your data is likely one of the indian spatial reference
systems, but I have no idea of which one:
http://prj2epsg.org/search?terms=India

In case fixing the SRS is not an option for you, there's the second possibility
of disabling map wrapping, you have to add this parameter to your java
virtual machine startup options:
-DENABLE_MAP_WRAPPING=false

Btw, please avoid posting the same mail three times in a row next time.

Cheers
