email -ext plugin: startup warnings after cleaning up

[Matthew...@diamond.ac.uk]

I was previously running version 2.15 of the email-ext plugin. I ran the groovy script described in https://issues.jenkins-ci.org/browse/JENKINS-11061 (to remove $PROJECT_DEFAULT_RECIPIENTS), and then upgraded the plugin to version 2.16 (two changes at once - never a good strategy). Now, I get a stack trace on Jenkins startup (details follow). Is there a problem with the script I ran, and if so, what's the best way to fix it?
Thanks

Edit config.xml and remove the recipientList item from the email-ext configuration.

[Matthew...@diamond.ac.uk]

I found that I also needed to remove the recipientList item from hudson.plugins.emailext.ExtendedEmailPublisher.xml, in addition to removing it from all the job config.xml’s.
