]
Chris Bredesen commented on HHH-2680:
-------------------------------------
A workaround is to manually copy the BLOB data after the merge. Line 94 shows the bug:
session.merge(domain); // changes blob value to 44
Changing it to this avoids the problem:
Domain merged = (Domain) session.merge(domain);
merged.setBlob(Hibernate.createBlob(domain.getBlob().getBinaryStream()));
Blobs not updated on Session.merge() for detached instances
