Caused by: java.sql.SQLException: You can't specify target table 'CONTENTPROPERTIES' for update in FROM clause原因
This is a problem caused by MySQL 5.7 which has new rules related to syntax. From Supported Platforms, Confluence 5.9.x only supports MySQL 5.6.x and 5.5.x (not tested with 5.7).
ソリューション
Migrate to MySQL 5.6 or 5.5
