Impact on existing functionality and JARs

While core functionality remains unchanged, some existing JARs like ant.jar are affected due to compatibility issues. The most straightforward solution is to upgrade the affected JARs to newer versions that are specifically designed for Java 25. These updated versions are likely to address the conflicts and ensure compatibility.

Diagnostic and testing in Maximo Manage

While upgrading to Java 25 does not introduce any functional changes, it is crucial to thoroughly test customizations, reports, automation scripts, and web services to ensure everything functions smoothly and without issues. For more information, see Diagnostic and testing in Maximo for Java 25. 

Industry solutions and add-ons

Maximo Industry Solutions and Add-ons are also transitioning to Java 25. Ensure that you upgrade to the corresponding versions to maintain compatibility. For more information, refer to the respective industry solution or add-on documentation.
 
Recompiling Java customization

Recompile your classes with Java 25. Recompiling helps ensure compatibility with updated APIs, catches outdated constructs early, and allows you to benefit from modern language features and improved bytecode performance.
