Only a subset of the JPA annotations are supported. These are the annotations that are supported:

• Basic
• Cacheable
• Column
• Embeddable
• Embedded
• Entity
• Enumerated
• GeneratedValue
• Id
• JoinColumn
• JoinTable
• ManyToMany
• ManyToOne
• MappedSuperclass
• OneToMany
• OneToOne
• PostLoad
• PostPersist
• PostRemove
• PostUpdate
• PrePersist
• PreRemove
• PreUpdate
• Table
• Transient
• Version

There is no support for embedded types. Unique/index constraints must be placed on the field/method level. Advanced JPA features are not yet supported such as embedded types, mapping via @JoinTable to secondary tables to define relationships (outside of ManyToMany).
