Migrate Hibernate 5.2 to JPA 2.1

I want to remove direct Hibernate references from my Java EE 7 server application so that I will not have a compile-time dependency on hibernate-core in the future. As a replacement, I want to use the plain JPA API.

So far, I figured out that org.hibernate.annotations.Cascade and org.hibernate.annotations.CascadeType can be mostly transferred to the cascade-parameter of JPA's @ManyToOne or @OneToMany. Also, org.hibernate.annotations.Type seems to be replaceable by a suitable JPA @Converter.

However, there are more usages of Hibernate in my code where I am struggling more:

Could you give me any hints if and how those can be migrated to JPA? Alternatively, links to a Hibernate → JPA migration guide/tutorial would be very appreciated.

You can't replace these unless you want to rewrite your application. You shouldn't try to avoid these annotations IMO as that would just leave you with a bad performing application that is probably still not portable. Hibernate is the de-facto JPA implementation, so I doubt you want to move away from it.
