Steps to reproduce:

• Start up a clustered instance of confluence with plugin-repository plugin disabled.
• Enable plugin-repository plugin
• install "Dynamic Table" plugin through plugin-repository plugin - it reports the success
• on the same node click on any admin link eg. Languages
• you will see this:

If you use another node you can navigate to Languages without getting the exception. Might be related to CONF-13021.
