April 2025 monthly summary for corretto/corretto-8. Delivered targeted fixes and hygiene improvements to stabilize builds and clarify release packaging. Key outcomes: 1) JavaFX build stability: Disable problematic GStreamer/GLib sources in the JavaFX 17u build by injecting #error directives; this patch reduces build-time failures due to modified sources (commit 85fecfb8899dd5863854a9f2f85e2be14cadbd41). 2) Patch maintenance and correctness: Standardize patch artifacts and patch application behavior by renaming patch files to include the .patch suffix, correcting paths (javafx.media -> media), and updating copyright years (commits 0f4eec41845d050393c9754f03870b63ce978834; 4050cd3ebf8cdee8e1c418d1aa1cce5e985be21d; 2f9c11a5f04ee5e72b5c5c1df2be0a4ab557448a). 3) CHANGELOG/documentation: Update CHANGELOG.md to document the Amazon Corretto 8.452.09.1 release and Linux alternatives packaging fix (commits d23d3296d4f0a1042e071049fad39c584abd261f; 1eeffb8385490f488db58e852c0ae23b7dec58ad).
