A year after I reported https://github.com/jakartaee/mail-api/issues/665 upstream, a fix has finally been released in Jakarta Mail 2.1.3, allowing me to finally migrate the Jenkins ecosystem to Jakarta Activation 2.1.3, Jakarta Mail 2.1.3, and Eclipse Angus. This in turn finally eliminates the namespace conflict with the old javax plugins, resolving JENKINS-70627. The change has been deployed to production users for a few days with no reported issues. Thanks to Olivier Lamy for making the first commit in this direction over a year ago.
There is some low-priority cleanup work remaining, which I do not have the energy to do right now. JENKINS-72822 describes how to remove the last remaining workaround in this subsystem, something that is possible now that we are on Jakarta Activation 2.1.3 if the Jakarta Activation API plugin and Jakarta Mail API plugins were first merged into a single plugin. Upstream has assured me the workaround is part of a stable API and should continue to work, so I see no urgent need to work on this in the short to medium term. But if anyone is interested, once the plugins are combined into one, removing the workaround should be as simple as deleting all Java files from Jakarta Mail API plugin. The other bit of cleanup is migrating Mock JavaMail usages to the new APIs. This is low priority since it only affects tests and is not blocking any production users or BOM/PCT work. I filed a handful of PRs to update the most important consumers in the jenkinsci GitHub organization, but for the sake of posterity the instructions are as follows: 1. Upgrade jakarta-activation-api and jakarta-mail-api to 2.1.3-1 in a <dependencyManagement> section (until these are in a BOM release). 2. Upgrade mock-javamail to 2.2, adding exclusions for jakarta.activation-api, jakarta.mail-api, angus-activation, and angus-mail. 3. Ensure the dependency on jakarta-mail-api is above the dependency for mock-javamail, after configuring Surefire to use system property variables for mail.smtp.class, mail.pop3.class, and mail.imap.class.
