> I don't think there 17.0.3 ever will be available from openjdk.java.net

These are the official upstream builds by the updates project built by Red Hat. Not to be confused by Red Hat Java, not to be confused by the AdoptOpenJDK/Adoptium builds. These can‘t be hosted on openjdk.java.net because they host only builds done by Oracle, not to be confused by Oracle JDK.

This site doesn't provide anything newer than OpenJDK 11 and references the Adoptium projects for July 2021 and future releases. But Adoptium only provide their own Temurin distribution. Looks like a dead end for an OpenJDK 17.0.3 upstream build.
