    • jenkins from version 1.502
      crowd 1.3-SNAPSHOT

      As described here: http://jenkins.361315.n4.nabble.com/Getting-NoSuchClassDefFoundError-for-ehcache-td391329.html, the spring-context-support JAR that is now (from version 1.502 on) packaged into the jenkins.war is loaded instead of the one from crowd/WEB-INF/lib. So it does not find classes from the ehcache JAR packaged only in the crowd/WEB-INF/lib.

      (see attached jenkins.log for complete stack trace)

      Two possible solutions:

      1. remove the spring-context-support JAR from jenkins.war/WEB-INF/lib
      2. switch class loader lookup order to search "plugin/WEB-INF/lib" first (this way it would be possible for plugin developers to override JARs delivered with the jenkins core)

      This issue prevents me from using the newest jenkins versions (starting from 1.502).

          I first encountered this problem in an upgrade to 1.497.

          Has anyone got any Jenkins LTS version beyond 1.480.2 to work? 1.480.2 seems to be the last LTS version that works with the crowd plugin.

          I got latest LTS Jenkins to work with the latest crowd pluging, but I have to delete spring-context-support JAR as the possible solutions 1. says.

          So is this a problem with core or with the crowd plugin?

          I don't understand the nabble link above. It is from 2009, and it seems the problem was FIXED at that time. So why has it suddenly resurfaced? Can we apply the same "fix" again?

          Why was that jar file included again? Maybe related to this commit? (which is from 6 months ago):

          Anyone know if this is going to be fixed by chance or if we just need to plan on implementing the workarounds in the future?
