    Description

      A configuration error can lead to a mysterious NPE:

      java.lang.NullPointerException
      	at org.apache.logging.log4j.core.appender.db.jdbc.JdbcDatabaseManager.setStatementObject(JdbcDatabaseManager.java:753)

      Throw a AppenderLoggingException instead, like other places in this class.
