Here are some more examples of differences between annotations in Java and Kotlin (using JPA2 annotations):

// java: 
@OneToMany(cascade = {CascadeType.REMOVE, CascadeType.PERSIST})
@JoinColumn(foreignKey = @ForeignKey)

// kotlin:
@get:OneToMany(cascade = arrayOf(CascadeType.REMOVE, CascadeType.PERSIST))
@get:JoinColumn(foreignKey = ForeignKey())
