      I have found some bugs inside jboss when I access datasource remotly.

      1. The code bellow throws NullPointerException when the blob field is empty. failed on org.jboss.resource.adapter.jdbc.remote.WrapperDataSourceService:553
      Code:

      Blob blob = resultSet.getBlob(column.name());
      bytes = blob.getBytes(1, (int)blob.length());

      2. The same code above does not return the contents of the blob when the blob is filled.

      3. There is a failue on org.jboss.resource.adapter.jdbc.remote.SerializableInputStream:266
      Correction should be Code:

      return read(b, 0, b.length);
