Java socket server: Not much progress since last meeting, due to start-of-semester work. Looking at the best way amongst several possible approaches to marry the DDF protocol code to these components.

https://shibboleth.atlassian.net/browse/JOIDC-50
- First thoughts on this: a new configuration property for a function that feeds profile configurations
- A lesson learned from the incompatibilities with the legacy tokens: make sure that the endpoints can handle prefix-configuration changes
- The prefix approach doesn’t work with the JWT access tokens (JOIDC-7)
JOIDC-21: Use token authentication for OIDC dynamic client registrationClosed
- The admin-flow approach (input: JSON, output: token compatible with some profile) could be useful in other parts too → Trying to make the structure generic
- The first functional PoC progressing

Heads up: Maven 3.8.2 is broken: JPAR-185: Site builds are not compatible with Maven 3.8.2Open
Initial details for Spring 6 have been announced: https://spring.io/blog/2021/09/02/a-java-17-and-jakarta-ee-9-baseline-for-spring-framework-6
- Short fluffy talk at Juergen Hoeller at SpringOne 2021 covers most of the following
- Java 17 baseline, will also support next two LTS after that (Java 23 and 29 in 2024 and 2027 respectively) (Spring 5 will not go beyond Java 17).
- Jakarta EE 9 baseline, implying
  - namespace change from javax to jakarta
  - Tomcat 10, Jetty 11 baseline
- The talks from Spring One (incl. Juergen Hoeller’s deeper dive on Spring 6) will be available 2021-09-07 at SpringOne.
- GA 2022 Q4
- M1 2021 Q4, i.e., in a couple of months. In principle, we could start a feature branch for Spring 6 at this point, or in general branch for v5. (Hibernate or some other dependency might be a sticking point; beta of next version of Hibernate expected in 2022).
- What about Spring Web Flow? I assume that’s Servlet-dependent and therefore won’t work vs. jakarta APIs as it stands.

https://shibboleth.atlassian.net/browse/JPAR-182
- Still chasing up Hibernate
- Probably need to make it into a verify plugin.
  - Sob
  - See no value in an end user program (“use this jar you downloaded to see if these jars you downloaded are safe”).
Complete the Nashorn Plugin V1.1
- Now using JDK
- But the GraalVM one also works
Some feedback on MetadataGen. So ready for release
Bug squashing:
- IDP-1854: Add a discovery option to the plugin commandClosed
- IDP-1830: Installer should check for outdated web.xml contentClosed
- IDP-1848: Expose any missing settings for LDAP poolingClosed
  - Note - properties in documentation but not in the properties file
- Blocked on IDP-1857: Log the plugins at IdP startupClosed
Wiki conversion

Jira down as of this AM
Working on https://shibboleth.atlassian.net/wiki/spaces/DEV/pages/2764865554
Started building and testing new Rocky 8 server and documenting that under https://shibboleth.atlassian.net/wiki/spaces/DEV/pages/2780070020
- Having issues with the server locking up, still doing A/B testing to pin down the cause

Maven Central
- deploying to Central : on hold
- working through hosting our repo via Apache rather than Nexus
  - isolates us from Nexus sec vulns (i.e. how we run Jenkins)
Containerizing Jenkins and Nexus
- working through using Docker Compose to run Jenkins/Nexus containers in AWS
