<p style="margin: 10px 0 0 0">The stream is an instance of org.hibernate.engine.jdbc.internal.BinaryStreamImpl (created from BlobProxy), and some custom logging shows that the same instance is being used twice. I have not dug deeper, i.e. to confirm if reset() is being called to rewind the stream or if the same stream object is supposed to be used twice etc.</p>
