For folks on RHEL, the java-17-openjdk package for RHEL 8 has been updated: https://access.redhat.com/errata/RHSA-2022:1445.

> The official OpenJDK project lists the planned release date of 17.0.3 as April 19th, still the latest available GA release is 17.0.2

> (https://wiki.openjdk.java.net/display/JDKUpdates/JDK+17u).

I don't think there 17.0.3 ever will be available from openjdk.java.net; there's no LTS for upstream builds, and since Java 18 is out already, no further builds of 17 should be expected there. IMO, this warrants some clarification on that site though.
