    Andrus Adamchik commented on CAY-1125:
    --------------------------------------

    Can you try remapping the DbAttribute type from SMALLINT to INTEGER. I think this is what causing the problem...

    > Key: CAY-1125
    > URL: https://issues.apache.org/cayenne/browse/CAY-1125
    > Project: Cayenne
    > Issue Type: Bug
    > Components: Cayenne Core Library
    > Affects Versions: 2.0 [STABLE]
    > Environment: Ubuntu Linux 8.04, Java 1.6.0_07, MySQL 5.0.51a-3ubuntu5.1, MySQL Connector/J 5.1.6

    > When trying to retrieve the value of a column that is of type "SMALLINT UNSIGNED" an exception of type com.mysql.jdbc.exceptions.jdbc4.MySQLDataException is raised.
    > This only happens if the value on that column is greater than 32767, since it overflows the Java Short type (that is always signed).
    > Forcing the type to INTEGER in the map.xml changes anything.
    > It seems that Cayenne is using a getShort() when it should use getInteger() (the later is always needed when using the unsigned version of SMALLINT in the database, doesn't it?).
