cannot deserialize from Object value (Grallvm native executable)

调研方向
复现解析 books.yaml 的原生可执行文件,然后从 OpenAPIParser.readLocation 经过 SwaggerConverter.convert 跟踪故障,直到 ArraySchema 反序列化。将原生结果与常规 Java 解析器的结果进行比较,并确定需要什么才能让原生解析器在不抛出所报告异常的情况下返回已填充的 OpenAPI 对象。

描述
Using plain java graalvm native executables cause multiple issues. The parser mostly returns empty OpenAPI objects without any error. Only on one file I can receive an error. I tried to initialise swagger models at run time, but this did not help --initialize-at-run-time=io.swagger.v3.oas.models
It would be really cool to know how to use the swagger parser on plain native java.
