Spring Boot: Extending User with composed type leads to: cannot find symbol - method setUser

[mux-R]

Overview of the issue

I followed the instructions for extending a user from this page in the docs: https://www.jhipster.tech/user-entity/
In my case I'm adding 2 composed types but the same issue occurs with 1 composed type.

entity ModeratorUser {
  organization String
}
entity RegularUser {
  fullName String
}
relationship OneToOne {
  ModeratorUser{internalUser(login)} to @OnDelete("CASCADE") @Id User with builtInEntity
  RegularUser{internalUser(login)} to @OnDelete("CASCADE") @Id User with builtInEntity
}

The code generation itself is successful, However, compiling the generated source code fails:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /home/username/projects/bug-showcase2/src/test/java/com/mycompany/buguserresourceit/web/rest/ModeratorUserResourceIT.java:[181,25] cannot find symbol

  location: variable updatedModeratorUser of type com.mycompany.buguserresourceit.domain.ModeratorUser

[INFO] 2 errors

[INFO] ------------------------------------------------------------------------

The issue is that it's trying to call setUser(User) on ModeratorUser and RegularUser. However, the method is actually called setInternalUser(User) because the property is called internalUser.

• JDL is mandatory for bug reports. This will allow us to use automated tests and genarate the broken sample using jhipster from-issue command.

Motivation for or Use Case

I want to extend the User type because I want to have different kinds of users and I want each type to have different fields/properties/columns.

Reproduce the error

I'm creating a new application using:

jhipster jdl bugUserResourceIT.jdl

Then I run:

./mvnw
