In Net Client mode, negative values for stream length are accepted without an exception for
PreparedStatement.setAsciiStream()

                 Key: DERBY-3705
                 URL: https://issues.apache.org/jira/browse/DERBY-3705
             Project: Derby
          Issue Type: Bug
          Components: Network Client
    Affects Versions: 10.4.1.3
         Environment: Windows XP SP2, Derby trunk SVN checkout
            Reporter: Suran Jayathilaka
            Priority: Critical


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.
