With Java 11 being the next LTS, we finally made the switch.
Steps we followed:
- Upgraded build toolchain (Maven/Gradle)
- Verified compatibility of 3rd party libraries
- Switched from CMS GC to G1GC and later ZGC for select services
Benefits:
- Better memory handling under G1GC
- Support for
var, HTTP Client API, and modules (experimentally)Note: Spring Boot 2.1+ works well with Java 11.
