After spinning up a new master, emails sent by email-ext were not getting their variables expanded. In the Jenkins server log we were seeing an NPE from h.p.emailext.plugins.ContentBuilder every time email-ext attempted to send an email:
ERROR h.p.emailext.plugins.ContentBuilder - null java.lang.NullPointerException: null
After some debugging we found that privateMacros had a null in it. it gets populated here:
(We are using version 2.40.2 but the code is the same in master.)
Using the script console, when we dumped the value of hudson.plugins.emailext.plugins.ContentBuilder.privateMacros we could see the null, but also I noticed that every possible macro is there 5x. On our other hosts there is only one reference to each. This is the output I got:

We were able to work around the NPE by running hudson.plugins.emailext.plugins.ContentBuilder.privateMacros.remove(null) in the script console to remove the null value. But this duplication of references still seems bad.
danielbeck felt that this design of using privateMacros as a sort of cache of possible macros was prone to issues like this and might benefit from a redesign.
