Roman Coedo commented on JCLOUDS-979:
-------------------------------------
This bug was introduced with this commit
https://github.com/jclouds/jclouds/commit/5ad245dea56b94735cc85c792a19c7121a0eb7dd
which assumes that every local blobstore returns blobs with a ByteArrayPayload
or a FilePayload. This is not the case in JdbcBlobStore.
Changing the way this blobstore handles the payloads is not trivial, since jpa
doesn't support mapping big blobs, we have to chunk every payload and have a
special stream which make database calls to ask for more chunks when needed.
