Is your feature request related to a problem? Please describe.
Spring Framework v5.3.39 reached end of life. It would be better to upgrade to latest Spring Framework v6.1.

Please let me know the current plan(if any) on upgrading to Spring Framework 6 and the future plans of the Spring Framework in data prepper project.

@NMAP97 , This is a good point. One blocking issue is that Spring Framework 6.0 requires Java 17 and above. Currently, Data Prepper requires Java 11 as a minimum.

https://docs.spring.io/spring-framework/reference/overview.html

We have #3192 open to support Java 17 or 21 as a minimum starting in Data Prepper 3.0. So we won't be able to make this update until then.

For my understand, is there a particular reason you raised this issue? Is this blocking your usage of Data Prepper or were you interested in making changes to support this?
