Webconsole MemoryUsage stacktrace after Karaf 4.4.11 upgrade

After upgrading to Karaf 4.4.11, I’m seeing the stacktrace below in the logs. Additionally, I noticed that the bundle org.apache.felix.webconsole.plugins.memoryusage-1.1.0 now imports the package org.apache.felix.webconsole.servlet, but this package does not appear to be exported by org.apache.karaf.webconsole.console-4.4.11. This seems to leave the import unresolved after the upgrade. Could you confirm whether this is an expected change in 4.4.11, or if an export is missing from the Karaf webconsole console bundle? Kind regards, Steven ``` 2026-05-05 10:31:54,303 - [E.Framework ][FelixDispatchQueue] ERROR - FrameworkEvent ERROR org.osgi.framework.ServiceException: Service factory exception:
