If I read the code correctly, the regular expression for checking UUID URNs is matched to the complete original IRI string (e.g., "urn:uuid:3e5baa77-a990-4a34-85b5-b66246829d24") ( https://github.com/apache/jena/blob/main/jena-core/src/main/java/org/apache/jena/irix/IRIProviderJenaIRI.java#L270) rather than to the fragment trailing after "urn:uuid" that the comment suggests ( https://github.com/apache/jena/blob/main/jena-core/src/main/java/org/apache/jena/irix/IRIProviderJenaIRI.java#L255 ).
