      Description

      After upgrade to Community 201612 GA there are a lot of erros in connection to database

      ERROR [hibernate.jdbc.BorrowedConnectionProxy] [defaultAsyncAction7] Unusable connection proxy encountered: org.hibernate.jdbc.BorrowedConnectionProxy@246be667
       2016-12-21 13:57:35,411  ERROR [hibernate.jdbc.BorrowedConnectionProxy] [defaultAsyncAction12]
      

      (log file attached)

      This results in multiple failed transactions.
      The error happens in all sorts of transactions, but can be triggered by uploading a new version where it needs to start creating thumbnails.

      It also happens after the system has been used for a while (not immediately after a restart), and the number of active sessions is above 10.

      It happens both with MariaDB and mySQL, both with mariadb and mysql jdbc driver.
