Why does source/target compile successfully but fail on an older JRE?
KitForma editorial guide. Syntax and class-file targets do not by themselves prove that only the older platform’s APIs were used. A newer build JDK can expose a method absent from the supported runtime.
Step-by-step guidance
Syntax and class-file targets do not by themselves prove that only the older platform’s APIs were used. A newer build JDK can expose a method absent from the supported runtime.
Use the compiler release setting for the minimum supported Java platform, for example
maven.compiler.release=17 when Java 17 is your explicit support floor. Confirm the compiler plugin and JDK support that release. Replace newer API calls or deliberately raise the product requirement.
Test the packaged program on the minimum JRE, including optional execution paths. This does not validate third-party bytecode: a dependency may independently require newer Java.Sources and verification
