WARN      [org.twdata.pkgscanner.ExportPackageListBuilder] Package Scanner found duplicates for package 'com.atlassian.crowd.integration.seraph' with different versions. Files: studio-jira-host-components-101.2.jar and crowd-integration-client-2.2.0.jar

This is because studio-plugins/studio-host-components/studio-jira-host-components/src/main/java/com/atlassian/crowd/integration/seraph/StudioJIRAAuthenticator.java resides in Seraph's package which gets exported to the OSGi container. Imo it's not necessary for that class to be exported to the OSGi container, thus we could move it to its own package and configure it appropriately in webapps/studio-jira/src/main/patches/seraph-config.xml.patch.
