I am experiencing the same issue when updating Feign-core from 11.8 to 11.9: Tests work under 11.8 and fail with 11.9: ``` 'feign.Feign$Builder feign.Feign$Builder.invocationHandlerFactory(feign.InvocationHandlerFactory)' java.lang.NoSuchMethodError: 'feign.Feign$Builder feign.Feign$Builder.invocationHandlerFactory(feign.InvocationHandlerFactory)' at io.github.resilience4j.feign.Resilience4jFeign$Builder.build(Resilience4jFeign.java:61) ```...

We are also facing this bug for generator version 6.2.0, indeed caused by the `schemaCodegenPropertyCache` for arrays fields with the same name and different item types. Looking into a fix...

@alyelalwany we have quite some internal workarounds for OpenAPI generator bugs and this is one of them. We do this by extending `org.openapitools.codegen.languages.JavaClientCodegen` and specifically overriding the behavior of `org.openapitools.codegen.languages.JavaClientCodegen#fromModel`....

This would be awesome to have as it is currently the main reason why MyBatis entity objects often can't be immutable Java objects in our code base.

@gavlyukovskiy ignore the comments and last commit for now, I am applying the comments myself and want to play around with it a bit more adding lower level unit tests...

@gavlyukovskiy would it be nice if I prepare `json-masker.blaauwendraad.dev` to publish benchmark results and maybe some kind of public documentation page? We can also host our own JavaDoc there :-)

Since we don't really have new feature requests, in our vision the library is feature-complete, there is no point in improving benchmark set-up. We might do this later and then...

@jansupol do you have any update on this issue, perhaps? This is preventing us from updating Jersey to the latest
