bnodes mapping in JenaGraphAdaptor should not keep growing with every parsing of rdf files
------------------------------------------------------------------------------------------

                 Key: CLEREZZA-395
                 URL: https://issues.apache.org/jira/browse/CLEREZZA-395
             Project: Clerezza
          Issue Type: Improvement
            Reporter: Hasan


With every parsing of rdf files free memory is getting less.
The problem seems to lie in the JenaGraphAdaptor class
It has a member:
final BidiMap<BNode, Node> tria2JenaBNodes = new BidiMapImpl<BNode, Node>();

which grows each time a serialized graph get parsed.

My experiments with my test data show

At the end of the 1st parsing: Size of tria2JenaBNodes = 87200
At the end of the 2nd parsing: Size of tria2JenaBNodes = 130800
At the end of the 3rd parsing: Size of tria2JenaBNodes = 174400
