    ****************************************************************
    EclipseLink's DatabasePlatform.cursorCode is invalid for DB2
    Cursors. Instead of the default value (-10), Db2 expects the
    java.sql.Type to be com.ibm.db2.jcc.DB2Types.CURSOR(-100008).
    If CURSORs are used with DB2, the following exception will be
    thrown:
    ´´´
    Caused by: com.ibm.db2.jcc.am.SqlException:
    [jcc][10271][10296][4.24.92] Unrecognized JDBC type: -10.
