As per RFC 7047 :
<integer>
A JSON number with an integer value, within the range -(2**63)...+
(2**63)-1.

The <integer> range defined above will match the Long representation in Java
and hence any place the schema defines a <integer> datatype, it has to be
handled as a long.

The library does its role appropriately by populating the data as a long value.
It has to be handled on the Static typed schemas in the Open_vSwitch and
hardware_vtep schema directories.
