Scenario:

After a TDV upgrade, you see this error in your cs_server.log as a result of an execution of an introspected web service operation.  The error refers to Apache's Base64 codec.

Look in your installation path /apps/common/lib  for the presence of both of these files:
commons-codec-1.3.jar
commons-codec-1.9.jar

The commons-codec-1.3.jar file is a remnant of earlier versions of data virtualization prior to TIBCO.   You should only have /apps/common/lib/commons-codec-1.9.jar present in your installs of TDV through version 8.2, at the time of this writing.

Delete commons-codec-1.3.jar to resolve the Base64 error.  This file may have been unsuccessfully removed during the upgrade process.

This concerns an issue of installations and upgrades
