I don't know what it exactly means but I can at least provide a rewording. Quick expanation: The message is harmless and the developer could probably log it as INFO instead of WARN.

Pages are stored in XML. There is a small metadata storage (Content Property) in addition to this XML which plugins are allowed to use, mostly for optimization purpose. For example a plugin which counts the number of page views could store it in the page metadata. This way, it doesn't need to change the contents of the page itself and it doesn't create a version in the history. Besides, Confluence provides extra features to such plugins to lookup pages with such metadata and quickly perform operations.

In the current situation, this warning seems logged by your BSD plugin ("org.andya.confluence.plugins.metadata.PageUpdateListener"). Since its license allows the decompilation of the plugin, I was able to access the code and it seems the macros actually use the page's metadata storage to cache some data.

Some code of the plugin is triggered when you delete or trash a page, to remove the metadata introduced by the macro.

If this warning annoys you, you can mute it by going to Loggins & Profiling in the Confluence administration, entering the package name of the plugin ("org.andya.confluence.plugins.metadata") and setting its debug level to ERROR.

Morale of the story: BSD is love, BSD is life, BSD gets you helped.

Wow, that is a detailed and transparent description, thank you very much.

It's very reassuring. I'v changed the errorlog as you recommended. I will this also update in the Log-configuration, that this is also remembred on restart of confluence.

Thank you again for your help.




I was just curious how other plugins are developped, actually, it was fun ;)
