Oracle driver and BLOB types fail in real world scenario
--------------------------------------------------------

         Key: HHH-2237
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2237
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.0.ga    
 Environment: JBoss AS 4.0.4 GA, JBoss Portal 2.4 GA
    Reporter: Magesh Kumar Bojan
 Attachments: test.log

When JBoss Portal is started up using Oracle 10g (10.2.0.1) and using the Oracle JDBC driver (version 10.2.0.2), and using the JBoss Portal CMS module, if you upload a file, it throws IOExceptions. The file size is arbitrary and should be more than 100KB. Some of the IOExceptions thrown are and not limited to:

java.sql.SQLException: Io exception: Bad file descriptor 

and

java.sql.BatchUpdateException: Io exception: Read error

Please use the attached test.log for testing.

There is a workaround for this as in you can modify the BlobImpl like this and it works:

public BlobImpl(InputStream stream, int length) {
      byte[] bytes = new byte[length];
      try {
         stream.read(bytes,0,length);
      } catch (IOException e) {
         e.printStackTrace();
      } finally {
         try {
            stream.close();
         } catch (IOException e) {
            //ignore
         }
      }
      this.stream = new ByteArrayInputStream(bytes);
      this.length = bytes.length;
   }

This code is not optimized, but for those who feel they need an urgent fix, this works!
