Michael Dürig updated OAK-1189:
-------------------------------

    Attachment: OAK-1189.patch

Proposed patch with changed contract:

{code}
    /**
     * Returns a new stream for this blob. The streams returned from
     * multiple calls to this method are byte wise equals. That is,
     * subsequent calls to {@link java.io.InputStream#read() read}
     * return the same sequence of bytes as long as neither call throws
     * an exception.
     *
     * @return a new stream for this blob
     */
{code}

> {{Blob.getNewStream}} mandates the returned streams to be equal. Currently this is not implemented by any of our {{Blob}} implementations. 
> However, I think the contract is overly strict. We should probably adapt it to require the returned streams to be "byte wise" equals.
