Re: Investigate forking Spring Web Flow for IdP 5 ( https://shibboleth.atlassian.net/browse/IDP-1892?atlOrigin=eyJpIjoiMWE2ZmQ3YWU4NDRhNDkyZDlkZTI2YTBhNWJlODkyZTAiLCJwIjoiaiJ9 )

My fork of spring-webflow now uses the latest version of Gradle and uses the new publication system. Everything compiles and builds under Java 17, and I’ve fixed the terminal deprecations that showed up ( new Integer(2) becoming Integer.valueOf(2) ).

I’m moving on to adopting the new dependencies, starting with the current Spring Framework 6 milestone.

An immediate problem is that Spring Web Flow includes some classes that support Tiles 3 views via the Spring Framework integration for that technology. Tiles is now defunct, so the Spring Framework classes seem to have been pulled with no prior deprecation:

I don’t think they had any choice in this, as Tiles isn’t going to get an upgrade for the new EE namespace. I’m also pretty sure we don’t use this stuff so my plan is just to rip it out and see what happens.
