I just upgraded from Appian 7.5 to 7.10 on JBoss 6.4. On start up, the following

The error indicates your appian_log4j.properties under ear\\suite.ear\\conf\\resources makes reference to an Appian 7.5 class called com.appiancorp.common.monitoring.SystemMetrics$Layout which has been renamed in 7.10 to com.appiancorp.common.monitoring.AppServerSystemMetrics$Layout.

This happened because you also migrated the appian_log4j.properties from 7.5. That's not a good practice. If you wanted to preserve some custom loggers you should have merged them into the new file form 7.10. Copying files from old versions can cause issues.

In this case JBoss starts properly so it's nothing major but other files can cause an erratic behavior if copied over instead of merging.

Thank you. Problem is now resolved.
