Minor After today's upgrade from Jenkins core v2.265 => 2.270 and all plugins as well to latest versions (the previous upgrade was on November 6), I have seen the following log:
2020-12-10 12:02:22.766+0000 [id=31] WARNING o.s.c.s.ResourceBundleMessageSource#getResourceBundle: ResourceBundle [org.acegisecurity.messages] not found for MessageSource: Can't find bundle for base name org.acegisecurity.messages, locale en_US
Please note that it did not appear after the very first startup (with new versions) though :-o
jglick And I am also just naively guessing it has to do with JEP-227...
Here is more Jenkins startup log context:
