A few remaining vulnerable dependencies

[benjsmi]

@bestbeforetoday thanks in advance for your time on this.

Two PRs open that have both passed the checks. Should be helpful for keeping us up-to-snuff on the security/dependency side of things:

https://github.com/hyperledger/fabric-chaincode-java/pull/331

and

https://github.com/hyperledger/fabric-chaincode-java/pull/332

And also https://github.com/hyperledger/fabric-chaincode-java/pull/335

These are all good now. Thank you!
