Thanks for clarification and the fix. 

Just found another issue - when "Quote SQL Identifiers" is on, the generated 
SQL is incorrect. I guess the function should not be placed in quotations. E.g. 
here is a MySQL example:

  Property<Long> count = Property.create(FunctionExpressionFactory.countExp(), 
Long.TYPE);
  ObjectSelect.query(MyType.class).column(count).selectOne(context);

  bootique-http-38 o.a.c.l.CommonsJdbcEventLogger: SELECT `COUNT(*)` FROM 
`my_table` `t0` 
  bootique-http-38 o.a.c.l.CommonsJdbcEventLogger: *** error.  
  com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 
'COUNT(*)' in 'field list'
