[hibernate-dev] Re: [External] : Re: JDK 18 Rampdown Phase 2 & JDK 19 Early-Access Builds

Hey David, It seems the download links on https://jdk.java.net/19/ are out of date; the link for Linux / x64 in particular [1] is giving me a 404. This is making our continuous integration fail, so we might end up disabling JDK 19 tests unless we find a solution soon... Do you think you could look into this?
