Call Details

This week's call will use the Zoom system at GU, see ZoomGU for access info.


  1. Duration (or Instant/DateTime) parsing - JAXP vs. java.time



  • OSJ-265 - Getting issue details... STATUS
    • Unless we (really) bind our rules, tentative plan would be to do a new minor release of java-support 7.5.0, and a patch release of java-opensaml (and possibly java-identity-provider).  Concerns?


  • OSJ-269 - Getting issue details... STATUS
    • Fighting with standing up MySQL for testing
  • IDP-1357 - Getting issue details... STATUS
    • Testing system properties
    • Guiding some development for ldaptive 2.0


  • Finishing OIDC flow-tests, polishing, ...
  • Aiming at releasing the first official OIDC plugin version before end of March


  • Maven version now enforced:  JPAR-118 - Getting issue details... STATUS
    • Replaces older prerequisites element, so enforcing version 3.3.1
    • 3.3.1 was 2015-03-18, so five years ago.
    • I'd like to enforce something newer in the interests of consistent builds.
    • Maven versions: 



  • Work on IDP-1191.
    • Since servlet spec 3.0 (session tracking config is a bit more standardised since 3.0), setting session tracking mode to COOKIE (and only that) in web.xml, should not expose jsessionid unless bug. This is already being set by the IdP.
    • Not sure the impact of stolen JSESSIONID, ship_idp_session is more a form of ambient authority. Although is used by webflow for conversation state and shib session manager internals (needs more looking into)
    • Looked at the potential to steal cookies with injected JavaScript - unlikely - although httpOnly bypasses have existed in the past. Also injected script could steal any anti-csrf token if used - but can not see how JavaScript could be injected into the views (dynamic stuff is being escaped).
    • Will look at anti-csrf token - and or the impact of session surfing, as not sure how useful that is.
    • Will write something small up unless somebody tells me I am wasting time.


  • Out for much of last week.
  • Working through deprecations in custom schemas


  • LDAP test behavior works under Maven now, still get failures during "whole package" testing under Eclipse
  • JSPT-79 - Getting issue details... STATUS
    • Most uses of @Duration now gone, some long APIs left to clean up
    • Possible future work item: a standardized Spring context for tests to match runtime environment
  • Next up is ProfileConfig API consistency/cleanup


  • Wrangling Jenkins, Java. Still having trouble with Java 11 and Windows


  • No labels
