Hibernate: Could not deserialize – invalid stream header

For others with the same error (does not answer this exact question)

I experienced this error with hibernate 4.3 and 5.0.5 due to fields of type java.time.LocalDateTime, I have several entities using LocalDateTime, but only one of them caused the issue, I don’t know why.

It was fixed by adding the following dependency:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-java8</artifactId>
    <version>${hibernate.version}</version>
</dependency>
