Deprecations and Removals

Covers concrete removals: JEP 503 removes 32‑bit x86 ports because builds and CI lack test hardware; JEP 504 drops the Applet API but requires rewriting thousands of tests that used applets as test harnesses; JEP 421 deprecates finalization for removal because finalizers are untimely, impose GC overhead and enable resurrection; JEP 486 effectively disables the Security Manager (APIs remain as no‑ops, flags now throw), recommending OS‑level containers for running untrusted code.
