And obviously, changing in Master object string to {{@OneToOne(mappedBy = "master" ,cascade = ALL, fetch = EAGER)}}solved the problem.

Is anybody working on this issue? I’ll try to elaborate on the code but I’m new to Hibernate so I think it’ll take much time for me.

Is Anybody have ideas how to fix this? And I’ll appreciate if anybody can give the link in the docs if you can map one-to-one via only @PrimaryKeyJoinColumn without mappedBy
