FFM build requires Java 25, Jextract 25. Generates FFM bindings during configure. JNI is default when the requirements are not met or can be forced. Presets added for maven and FFM - JNI is default selection. Enhanced Maven options will work with either JNI or FFM New Workflows for testing and maven uploads. Extensive documentation changes for java.
