[BUG][JAVA] StackOverflowError in ExampleGenerator due to circular allOf references

[ainGitHub]

When processing OpenAPI schemas with circular allOf references, the ExampleGenerator throws a StackOverflowError due to infinite recursion between traverseSchemaProperties and resolveAllOfSchemaProperties methods.

Attach changed original 3.0/example_generator_test.yaml from core of project
example_generator_test.yaml

Simple example

    ExampleAllOfRecursionSchema:
      type: object
      allOf:
        - $ref: '#/components/schemas/ExampleAllOfRecursionSchema'
        - type: object
          properties:
            example_schema_property_composed_parent:
              type: string
              example: example schema property value composed parent
