[JENKINS-49069] Multibranch Pipeline project cannot copy scm.locations to new SubversionSCM in Jenkinsfile without cast to List<...>

The cast seems redundant. I'm not sure if this affects other fields, but scm.locations is what I use. I need to do some checking out on the node, but with slightly different parameters.

The failing checkout step:

            checkout  changelog: false, scm: [$class: 'SubversionSCM', additionalCredentials: [], excludedCommitMessages: '', excludedRegions: '', excludedRevprop: '', excludedUsers: '', filterChangelog: false, ignoreDirPropChanges: false, includedRegions: '', locations: scm.locations, quietOperation: true, workspaceUpdater: [$class: 'UpdateWithCleanUpdater']]

 

Produces following error:

Adding a cast to List<...> resolves the error:

            checkout  changelog: false, scm: [$class: 'SubversionSCM', additionalCredentials: [], excludedCommitMessages: '', excludedRegions: '', excludedRevprop: '', excludedUsers: '', filterChangelog: false, ignoreDirPropChanges: false, includedRegions: '', locations: scm.locations as java.util.List, quietOperation: true, workspaceUpdater: [$class: 'UpdateWithCleanUpdater']]
