*Hello Apache Fineract community,*
*I would like to propose upgrading the project from Java 21 LTS to Java 25 LTS (it is a NFR change). **This change is proposed because the following reasons:* - Java 25 is the current LTS (it was released September 2025). - Java 25 has improvements about performance, language features, security, longer support window, alignment with Spring Boot upgrades or dependencies. - Java 21 will eventually move out of free support and it will become less convenient for new contributors and adopters. - Evergreening compliance is required by Institutions that run the software on production environments - It is a best practice for having the technology aligned to the EOL of the base framework/product. *The changes that contains the PR are: * - Gradle toolchain languageVersion = 25 - Jib base image update (azul/zulu-openjdk-alpine:25) so then the Docker Hub images dev tag will be updated to java 25 (arm and amd64). - Modernizer module and ResolutionHelperTest required fixes - CI / GitHub Actions updates - Documentation (MD files). - Existing functionalities are working (green flag/checks after running the Github Actions) *As any technology upgrade there are risks and compatibility issues that must be highlighted* - Requires JDK 25 to build and run (The developer will require to upgrade the Java version and also the running environment will require the upgrade) - If you have developed third-party libraries and plugins they may need to be upgraded to Java 25 *These are the tickets for your review:* JIRA ticket: FINERACT-2734 https://issues.apache.org/jira/browse/FINERACT-2734 PR ticket: https://github.com/apache/fineract/pull/6215 *I welcome feedback about any concerns and especially your help with testing on different environments (MariaDB, PostgreSQL, different Operating Systems and/or multi-tenant setups).* *Thank you in advance!* *Victor Romero*
