Those floating releases were excluded from both the resolution cache and the JDK cache, so `cache-jdk` users lost caching entirely for them. A floating URL is a constant string, so it cannot serve as a cache identity on its own — a stale entry would be reused forever. Instead, derive a validator from the headers of the HEAD request that already resolves the artifact: the ETag when present, otherwise `Last-Modified` combined with `Content-Length`. Republishing changes the validator, which changes the cache key, so a new build is downloaded rather than masked. `getJdkReleaseIdentity` now falls back to that fingerprint before the URL, and the floating cache gates ask whether the release has a stable identity (checksum or fingerprint) rather than a checksum specifically. A floating release with neither is still left uncached.
