PreparedStatement method setNClob(int, Reader) causes HANG with 11g JDBC Driver

When using JDK 1.6 with the new 11G JDBC driver the following code causes a HANG to occur.

   // Get connection
   Connection conn = getConnection();

   // start test
   String lobContent = "WLS JDBC4 test for NClob.";

   String insertSql = "INSERT INTO nclob_table VALUES (?, ?)";
   PreparedStatement pstmt = conn.prepareStatement(insertSql);

   int loopCount = 10;
   StringReader sreader = null;

   try
   {
       for (int i = 0; i < loopCount; i++)
       {
           pstmt.setInt(1, i);
           sreader = new StringReader(lobContent + "-" + i);
           // Hangs here
           pstmt.setNClob(2, sreader);
           pstmt.execute();
           sreader.close();
           System.out.println("inserted a row..." );
       }
   }
   finally
   {
       if (pstmt != null)
       {
           pstmt.close();
       }
       if (conn != null)
       {
           conn.close();
       }
   }
 }

The hang occurs at this line of code:

pstmt.setNClob(2, sreader);

In order to avoid the hang you can use the following method:

• setNClob(int, Reader, long)

This then works fine when the following is used.

pstmt.setNClob(2, sreader, sreader.toString().length());
