After updating Hibernate from 3.6.2 to 4.1.10, I get the following exception:
The stream value is not the specified length. The specified length was 7, the actual length is 0.
Since this happened in the middle of our application I created a sample application to reproduce this.
I had started a forum topic https://forum.hibernate.org/viewtopic.php?f=1&t=1025471&start=0
but nobody answered, probably it was described too vague.
Now with the example project, the issue can be reproduced very easily.
