FFM (java.lang.foreign) went stable in JDK 22 (JEP 454), so the project may not actually need a JDK 25 floor. Drop maven.compiler.release 25 -> 22 and run the CI build matrix on both 22 and 25 to find out. If 22 is green, the supported floor can drop, widening the addressable audience substantially (most prod JVMs are on 17/21, not 25). Experiment only — not for merge as-is; report-driven.

Experiment — not for merge as-is. Tests whether the project builds + passes on JDK 22 (first stable FFM, JEP 454) as well as 25, to decide if the supported floor can drop from 25.

Most production JVMs run 17/21, not 25. If 22 is green, dropping the floor widens the addressable audience massively — the #1 adoption lever discussed for promotion.
