Thanks for putting together this upgrade @MikeThomsen. Upgrading commons-codec across all modules looks like the correct way to go. I noted one question about whether the explicit version number was still necessary in nifi-standard-processors/pom.xml. Otherwise the changes look good.

[exceptionfactory]

Is this specific version necessary with the version already specified in the root Maven configuration?

[MikeThomsen]

IIRC it was. I ripped out ALL of them and 4 modules still required it. IIRC, it was due to test vs compile scoping issues with <dependencyManagement> in the root pom.

[exceptionfactory]

Thanks, that makes some sense.

Thanks for the upgrade and improvement @MikeThomsen, looks good! +1 merging.
