Streaming data into LONG results in ORA-24307

Question

I am migrating an application to a new environment. During testing I am receiving the following error when trying to insert a record into an Oracle 8.1.7.4 table:
Error saving report: update BlobPiece osetpi(): ORA-24307: invalid length for piece
The table has a column defined as LONG. I am using a prepared staement and setAsciiStream to perform the insert. I have been able to determine that the error happens when the data being streamed exceeds 4000 bytes (i.e. 4001 bytes).
Connection to the table is made by using a datasource with the ORACLE_OCI driver. If I change the connection to use an Oracle thin driver, the insert is performed (code provided below).
I would prefere not to change the connection method if possible. Any help resolving this problem would be appreciated. Thanks.
Here is the insert code being used:
public void create(SavedReportImpl report, String userId)
throws ReportManagerException {
StringBuffer sql = new StringBuffer();
// NOTE: Must utilize a prepared statement since this insert contains
// an Oracle Long column type
java.sql.PreparedStatement statement = null;
String modelCd = report.getModel().getModelCd().toUpperCase();
if (modelCd.length() != 7) {
modelCd = " " + modelCd;
sql.append("INSERT ");
sql.append("INTO ");
sql.append("PRCT012 ");
sql.append("(");
sql.append("MODL_YR_NBR, ");
sql.append("PRICE_CD, ");
sql.append("MDSNG_MODL_DESGTR, ");
sql.append("EFFECTIVE_DT, ");
sql.append("REPORT_TP, ");
sql.append("REPORT_SUBTP, ");
sql.append("RESTRICTION, ");
sql.append("PRICE_DESC, ");
sql.append("VEHICLE_LINE, ");
sql.append("MODL_DESC, ");
sql.append("CURRENCY_CD, ");
sql.append("CURRENCY_NM, ");
sql.append("SOP_INDCTR, ");
sql.append("LAST_UPDT_USERID, ");
sql.append("LAST_UPDT_TMSTM, ");
sql.append("REPORT_HTML_STRING) ");
sql.append("VALUES (" );
sql.append("'" + report.getModel().getModelYear() + "', ");
sql.append("'" + report.getPriceCd().toUpperCase() + "', ");
sql.append("'" + modelCd + "', ");
sql.append("'" + dateFormatter.formatDatetoDBDateString(report.getEffectiveDate()) + "', ");
sql.append(report.getReportType() + ", ");
sql.append(report.getReportSubtype() + ", ");
if (report.getModel().getRestriction() == null || report.getModel().getRestriction().length() == 0) {
sql.append("NULL, ");
} else {
sql.append("'" + report.getModel().getRestriction().toUpperCase() + "', ");
sql.append("'" + report.getPriceCdDescription() + "', ");
sql.append("'" + report.getModel().getVehicleLine().toUpperCase() + "', ");
sql.append("'" + report.getModel().getDescription() + "', ");
sql.append("'" + report.getCurrency().getCurrencyCd().toUpperCase() + "', ");
sql.append("'" + report.getCurrency().getCurrencyNm() + "', ");
sql.append(report.isSOP() ? "'Y', " : "'N', ");
sql.append("'" + userId.toUpperCase() + "', ");
sql.append("'" + dateFormatter.formatDatetoDBDateTimeString(new java.util.Date()) + "', ");
sql.append("?) "); // LONG COLUMN TO BIND
//NOTE: only bind one column when there is an ORACLE LONG
try {
statement = connection.prepareStatement(sql.toString());     
String html = com.eds.csdd.util.StringUtils.replaceAll(report.getHTML(), "'", "''");
byte[] bytes = html.getBytes();
java.io.InputStream is = new java.io.ByteArrayInputStream(bytes);
statement.setAsciiStream(1, is, bytes.length);
int resultCode = statement.executeUpdate();
} catch (java.sql.SQLException sqle) {
throw new ReportManagerException(sqle.getMessage());
} catch (Exception e) {
e.printStackTrace();
throw new ReportManagerException(e.getMessage());                    
} finally {                                   
if (statement != null) {
try { statement.close(); } catch (java.sql.SQLException re) {}
Here is the connection code using the datasource:
public java.sql.Connection getConnection(String dataSourceName) throws java.sql.SQLException {
javax.naming.InitialContext               dsCTX          = null;
javax.sql.DataSource               ds1          = null;
java.sql.Connection                    conn          = null;
String dataSource = rte.getProperty(dataSourceName, "datasource","datasourcenotfound");
try {
     dsCTX = new javax.naming.InitialContext();
     ds1 = (javax.sql.DataSource)dsCTX.lookup("java:comp/env/" + dataSource);
} catch (javax.naming.NamingException e){
     throw new java.sql.SQLException("Naming Exception:" + e.getMessage());
if (ds1 == null)
     throw new java.sql.SQLException("datasource not provided");
else
     conn = ds1.getConnection();
return conn;
Here is the connection code using the thin driver:
public java.sql.Connection getConnection(String dataSourceName) throws java.sql.SQLException {
java.sql.DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
// open a connection to the database
java.sql.Connection conn = java.sql.DriverManager.getConnection (
                         "jdbc:oracle:thin:@###.##.###.###:1521:SID",
                         "userid",
                         "password");
return conn;
}

I tried it with the old 7.3.x JDBC driver and it works fine. I
also noticed after further testing that it sometimes worked
with the 8.0.4 driver. Looks like a bug in the 8.0.4 driver or
some wacky incompatibility.
