Blob
Blob.getStream()
method can be called
successfully several times. The persistence is done in a temporary file
or in memory - this is up to the implementation.
Blobs that are already persistent return themselves.
Persistence should update the internal structure of the Blob to make it persistent whenever possible and hence return itself whenever possible. This behavior cannot be guaranteed by every implementation however.
