Date Thu, 19 Mar 2009 11:53:50 GMT
Assert failure or ClassCastException in EmbedBlob when retrieving BLOB >= 32K
-----------------------------------------------------------------------------

                 Key: DERBY-4102
                 URL: https://issues.apache.org/jira/browse/DERBY-4102
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 10.4.2.0, 10.3.3.0, 10.2.2.0, 10.1.1.0, 10.5.0.0, 10.6.0.0
            Reporter: Knut Anders Hatlen


The code below results in an assert error (with sane jars) or a ClassCastException (with insane
jars):

        PreparedStatement ps = c.prepareStatement("values cast(? as blob)");
        int len = 32 * 1024;
        ps.setBinaryStream(1, new ByteArrayInputStream(new byte[len]), len);
        ResultSet rs = ps.executeQuery();
        while (rs.next()) {
            rs.getBlob(1);
        }

If len < 32K there is no error.
