      Description

      Opening this bug on behalf of Daniel Debrunner.

      -------------------------------------------------------------
      ResultsetMetaData.getColumnClassName() for CLOB and BLOB
      datatypes is incorrect.
      BLOB: CLOB:
      jcc: java.sql.Blob java.sql.Clob
      Derby: byte[] java.lang.String

      Derby's embedded JDBC driver returns the incorrect class
      names for BLOB and CLOB columns in a ResultSet when using the
      ResultSetMetaData.getColumnClassName() method. Note that the
      ResultSet.getObject() method calls are not currently supported
      for BLOB and CLOB.
