DAIKON 8 UPGRADE GUIDELINE

Why ?

Daikon 8 is the first release based on Spring Boot 3 and Java 17. This two upgrade comes with a lot of breaking changes.

Replacing all javax.* imports to jakarta.* imports
- Be aware that only Java EE javax packages are replaced by jakarta packages. For plain JDK packages such as javax.sql.* and javax.crypto.* they do not need to get replaced.
