Not generating all fields from class when having children/sibling of same type

[runarhk]

I have created a simple setup reproducing the where we have a class a that implements an interface A , having a field that has type A .

Steps to Reproduce

1. Clone supplied repo
2. run gradle assemble
3. notice missing fields in type TestImpl1 in generated file at build/classes/java/main/META-INF/swagger/hello-world-0.0.yml

Expected Behaviour

The field name woopsie should be in the TestImpl1 type with type: $ref: '#/components/schemas/TestImpl1'

Actual Behaviour

The field woopsie is missing entirely. This is also the case for lists of same type.

For some reason adding a generic type to the interface, like so: TestInterface<T> resolves the issue.

Environment Information

• Operating System: Linux Mint 20 Cinnamon
• Micronaut Version: 2.2.1
• JDK Version: openjdk 14.0.2 2020-07-14

Example Application

The field woopsie is private, why would it be included in the public schema?

[runarhk]

thanks for quick reply @graemerocher, i forgot to push the getter and setter which I added after removing lombok to get the test project as slim as possible. Pushed now ;)

This happens because when the whoopsie field is visited, the TestInterface type is also being visited in progress, and there is a recursion break to stop processing it.

Not sure what solution could be applied here.

[runarhk]

Makes sense. But how come it works if I add a generic type to the interface?

[alvarosanchez]

I guess that in that case, it goes through a different code path since TestInterface<T> != TestInterface
