Spring Boot 2.7 is approaching EOL.

Describe the solution you'd like

Upgrade to the latest Spring Framework. Upgrade to Spring 6 and Spring Boot 3.

Upgrade Spring Framework and upgrade dependencies to keep with that. This includes

• Spring Framework 6
• Spring Boot 3
• Java 21
• Apache Tomcat 10
• FreeMarker
• HTTP Proxy
• Tuckey
• ESAPI
• FileUpload
• Groovy 4, see Upgrade to Groovy 4 #5876
• Anything else that breaks with the javax to jakarta change

Note: Spring Boot 3 has Groovy dependency 4.0.11. We may need to upgrade Groovy.

@phuongnq yes, it's in the plan #5876

These are some libraries I have found so far that are non-compatible with Jakarta 9+ (required by spring 6)
ESAPI
Tuckey (url rewrite)
Freemarker
smiley-http-proxy-servlet
Apache commons - fileupload

These are some libraries I have found so far that are non-compatible with Jakarta 9+

• ESAPI
• Tuckey (URL rewrite)
• FreeMarker
• smiley-http-proxy-servlet
• Apache commons - fileupload

Due to the above, we must wait until our dependencies are updated to Jakarta 9.

I will close this ticket for now.

@sumerjabri I have checked the list.
For ESAPI, please note that there is no change regarding the version. We only added the flag <classifier>jakarta</classifier> to support it. Refer to https://github.com/ESAPI/esapi-java-legacy/wiki/Using-ESAPI-with-Jakarta-EE-Servlet-API-Specification-5.0-and-later#with-maven for the detail
