  1. Multiple CVE reports published for the Spring Framework



  • SOAP Client and SAML 2 Artifact decoder
    • Lots o' progress.  It's functional now in SP testing.  Still some work remaining on TLS vs signing, plus some unit tests and other odds/ends.
    • When we ship this in 3.4, should we enable the artifact index in batch metadata resolvers now by default?  There are arguments both ways.


  • OSJ-227 - Getting issue details... STATUS  
    • Fix pushed to cryptacular


  • Java 9 now "old and busted":
    • 9.0.4 last patch release.
    • I'd nevertheless suggest that we continue to cross-test against Java 9 until we think we have moved completely past it; Java 11 release perhaps?
  • Java 10 is "the new hotness".
  • Java 11:
    • "Proposed to target Java 11": new HTTP client, incubated as JEP 110, now JEP 321. Introduction here. Includes HTTP/2, Not clear if this is actually a replacement for Apache HttpClient for our purposes, but that seems to be the intention. Do we want to investigate, given that the Apache client needs to be bumped anyway?
  • New wiki page on Java Product Platforms:
    • Please review; I'd like to convert this to policy "soon" in some sense. Agenda item next time?
    • Critical decision points:
      • What we say about support of post-Java-11 non-LTS releases
      • Support of Java 11 by Java 7 platform
      • IdP V4: Java 8 or Java 11?
  • New set of wiki pages on Java Versions:
  • JPAR-116 - Getting issue details... STATUS  from last meeting: any thoughts since then? If not, will remove links to our products from parent project and rebuild them in each dependent project.
  • Researching OAuth, OIDC. Brain hurts.



  • SP Odds and Sods.  
  • SSPCPP-761 - Getting issue details... STATUS  
  • To paraphrase Ian  SSPCPP-730 - Getting issue details... STATUS  encoding: Brain hurts


  • SP package mirroring
  • SSPCPP-731 - Getting issue details... STATUS , 8 hours for one missing character
  • SSPCPP-350 - Getting issue details... STATUS
  • Exploring dynamic metadata in IdP, several issues opened
  • joda-time replacement


  • Not much change since last week
    • Jetty 9.4 tests pass on Windows
    • Some Java 10 tests do not
    • Reviewed Jetty and Tomcat default TLS cipher suites and protocols
    • TODO Windows and conditional:resources
  • Prob will ask Ian to take a second-look at Jenkins' Windows Slave config and OpenJDK JAVA_HOME
  • Jenkins : should we attempt building the IdP including the Maven site with each version of Java ?


  • No labels
