Currently the packaging guidelines for Java packages say this under the BuildRequires and Requires section:
Java binary packages or their dependencies MUST have Requires (generated by RPM or manual) on:
java-headless or java-headless >= 1:minimal_required_version
However, on modern Fedora, the jpackage-utils package has been renamed to javapackages-tools (which obsoletes and provides jpackage-utils). So, moving forward, really the guidelines should be updates to reflect this. I propose changing the bullet point which is currently jpackage-utils to javapackages-tools. I haven't made a draft for this trivial one word change.
I've gone ahead and made this change; javapackages-tools is available in all supported Fedora versions.
Thanks for letting us know.
