HHH-14725 Fix reset handling on BlobProxy

[Naros]

https://hibernate.atlassian.net/browse/HHH-14725

[beikov]

How about wrapping an InputStream to make sure closing only happens at the end of a TX when we do resource cleanup in Hibernate? If we see that the InputStream doesn't support marking, we could read the contents first into a byte[] and then serve data from there, or alternatively, write into a temporary file and serve data from that.

Is there maybe an ETA when this will be merged? We have encountered an issue with exactly this problem recently.

Our workaround for now is: We refresh the Entity with the Blob using the EntityManager before operating on the Blob's InputStream/Bytes.

Another workaround is to use a Session and get the Entity with the Blob from the Session and then operate on the InputStream / bytes[].

Hi @beikov do we have another proxy type that does this so I can use that as a reference guide?

It's fine, let's merge this as soon as tests succeed.

The test seems to fail @Naros
