Does Hibernate 3.1 close the Blob InputStream once the Blob is persisted?

Given the following...
FileInputStream fileInputStream = new FileInputStream("filename");
Blob blob = Hibernate.createBlob(fileInputStream);
entity.setBlob(blob);
entityManager.persist(entity);

The FileInputStream needs to be closed so I need to know if I need to close it or if Hibernate is closing it.

You can call close() on the input stream. If it is already closed, it will ignore the call.
