Upgrading to Jenkins LTS 2.150.2

Possible authentication problems

The security fixes in 2.150.2 require that security realms call SecurityListener#authenticated or SecurityListener#loggedIn after successful authentication. If a security realm does not do either, sessions will be invalidated immediately, and users logged out again.

To disable this security fix when using a security realm that does not call SecurityListener, set the Java system property jenkins.security.seed.UserSeedProperty.disableUserSeed to true.

Affected plugins and their status is tracked on the Jenkins wiki.
