Getting null pointer exception while creating JSONRPCCLIENT object in bitcoind

Class for creation of JsonRpcClient object for connecting my application by bitcoin test net already installed bitcoind and sync it with testnet as well from main network of bitcoin. Trying to create unique wallet address but getting null pointer exception as i can observe values are not being used from application.properties file i m using spring tool suite and maven dependencywf.bitcoin bitcoin-rpc-client 1.1.0

I got my solution actually the problem was of version i was using rpcport which is changed to test.rpcport for test net from bitcoind version 17.0 hence bean were not getting the connection from my localhost server causing null pointer exception.
