After upgrading to Confluence 7.10, you see a message that a number of your apps failed to start up.
Cause
In Confluence 7.10 we upgraded the version of Xstream bundled with Confluence. This was a major upgrade that impacted some apps.
See XStream 1.4 upgrade for full details of the change.
Workaround
We recommend upgrading Confluence in a test environment first, and checking that all your apps start up and work as expected. If you encounter a problem, you may be able to upgrade that app prior to upgrading Confluence, if the vendor has made a compatible version available.
If you do find an app doesn't start up, you'll need to:
upgrade the app, if a new version is available on Marketplace, or
contact the app vendor for assistance.
