HUDSON is not updating the relevant JIRA issues with back pointers to builds
when the perforce plugin is configured for SCM. From the plugin guidelines
(http://hudson.gotdns.com/wiki/display/JENKINS/JIRA+Plugin) it appears that the
JIRA plugin is performing a match on the change text to relate this to a
specific issue in JIRA, but when Perforce is used for SCM the change detail now
shows changelist numbers instead and the detail required to match the issue in
JIRA is only displayed when hyperlinking from the changelist number. (I think it
needs to use the Perforce Job name to match to the issue key in JIRA)
