Somewhere between version 1.28 and version 1.32 of the Subversion plugin, the RevisionParameterAction started being ignored. This action is used by upstream builds to limit the revision that will be fetched by downstream builds - to stop downstream builds getting ahead of upstream builds. Specifically, the Parameterized Trigger Plugin and the Tracking SVN Plugin both use this action.
A vanilla installation of Jenkins 1.428 (which is bundled with Subversion plugin 1.28) works fine. Upgrading the Subversion plugin to 1.32 breaks.
