Hi Stephan,
thanks for your kind reply. I think you correctly described the issue I'm
having.
It would be great if the JPA processor could support the "hasStream" flag.
At the moment, my JPA entity has a field defined as follows

@Basic(fetch = LAZY)
@Lob
@Column(length = 4001) << this is required for a database issue, which
requires length > 4000 bytes
private byte[] binaryData;

It would be great if anyone could clarify whether the stream feature is
implemented for JPA processor
Thanks a lot
Regards
Vincenzo
