      Description

      This is related to Cloudscape bug 4250.

      Pass negative length as the stream length for various setXXXStream methods should throw an exception. But in Net Client mode, passing a negative value as stream length to PreparedStatement.setAsciiStream() doesn't throw an exception.

      e.g. //from store/StreamingColumn
      PreparedStatement ps = prepareStatement("insert into "
      + "testLongVarCharInvalidStreamLength11 values(?, ?, ?)");
      ps.setInt(1, 100);
      try

      { println("===> testing using setAsciiStream with -2 as length"); ps.setAsciiStream(2, fileIn, -2); // should throw exception here but doesn't. }

      This issue has been fixed for embedded mode, but not for client mode.
