Duplicates for packages in Jira

[Ivo]

Hello,

after upgrading from jira 8.5 to 9.6 I am getting warning about duplicate packages. Basically  I know how to handle the issue I just don't know which of the files should be kept or removed. There is my log excerpt:

javax.activation-api-1.2.0.jar and jaxb-api-2.3.1.jar should be removed

This worked for me, you no longer see the alert in the logs. Update the application from 8.21 to 9.6

Thanks
