### Change While trying to speed up parsing of RDF/XML, I profiled the parsing process. It seems that resolving/parsing IRIs is one of the most time consuming parts in the whole process. When trying to look into `org.apache.jena.iri.impl.LexerPath#yylex`, I found hat the whole file has been" generated by JFlex 1.4.3 on 04/03/12". Fortunately, JFlex is still actively developed and the latest release is JFex 1.9.1 from 2023-03-11. `NotesAFS.txt` explains how to genereate the code with JFlex. But maybe no one has tried the process for 12 years now. I don´t know if the "maven jflex plugin" was available in 2012 or if there is a reason, why JFlex has not been integrated in the build process, Since Jena-Iri is a core part of the Apache Jena libraries, I think it may be wise to ensure, that the generated code is reproducable. Would it be a good idea to integrate the "maven jflex plugin" instead of the manual process? PS: I could not find any other Java IRI parser library, except for RDF4J. ### Are you interested in contributing a pull request for this task?
