iText 7 licensing and jackson-* jars

Question

We are using Coldfusion 2021 and iText 7.4
When loading the license, I get the error

_objectFieldValueSeparatorWithSpaces

I have finally nailed it down to the fact that iText uses Jackson .jar files version 2.12 while ColdFusion uses the same .jar files version 2.8.

Question... will Coldfusion work properly with jackson 2.12?

I'm done with my conversion.  The Jackson jar file was the only real issue.  Working on a suggestion from Charlie Arehart, I moved the iText version of the jar file ahead of the Coldfusion version in the classpath, leaving all of the other iText required class files at the end.  This appears to have resolved the issue, and I have not found any other consequences.

Who knows? Try it out and let everyone else know!

I doubt Jackson is going to cause problems for anything other than iText, which uses the latest Jackson version to avoid a databind vulnerability I think. So honestly I would back up the existing Jackson version, put in the new one, stop CF, delete everything in the cfclasses folder, delete anything in the classes folder if there is anything, then restart CF. It should be easy enough to roll back if there's any problem, especially in a development or staging environment.
