Confluence Upgrade (5.1.5->5.2.3) Error logged by PluginLoadersFactory during startup

Gavin Fowler Aug 15, 2013


I've upgraded my confluence instance from 5.1.5 -> 5.2.3, the upgrade was sucesful, and i have a runnign instance. HOwever, reviewing the log files shows an error is reported on start-up.

2013-08-16 09:27:39,244 ERROR [main] [atlassian.confluence.plugin.PluginLoadersFactory] get Unable to load extra plugins from  specified in -Dconfluence.plugins.extra.bundled.locations. file not found or unreadable

Can anyone give insight into what the error means and where to look to implement a resolve, it seems to me the error is refencing an empty / blank object as it reads "..plugins from specified in" (NOTE missing reference between the words 'from' and 'specified')?

Many thanks!

Hi Gavin,

The error is harmless, but we're seeing it reported in the logs at startup on the newest versions of confluence. It might be a developer flag that was left in by accident. We've created a bug report for it internally.
