Hi all, Was having a look at the pull requests and issues for Configuration, and found one from Dependabot where it's updating mailapi/javamail from 1.6 to 2.0.1 (2.0 was released Oct 2020 [1]).
The 2.0 release includes a change in namespace, from javax.mail.* to jakarta.mail.*. I created CONFIGURATION-813 and also included a quick fix and pushed to the Dependabot pull request. I am working more with Python and JavaScript these days, and not entirely sure what is the path for the migration to Jakarta namespace in Commons components. So I tried a fix that I believe will work with either javax.mail or jakarta.mail (catching ClassCastException... defaulting to the new jakarta.mail, etc). Feel free to provide any feedback here, on JIRA, or directly in the GitHub UI as a review. Thanks!
