v2.8.14 ignoring @Schema annotation

[cavazos-apps]

Describe the bug
After updating from v2.8.13 to 2.8.14, the @Schema annotation appears to be ignored. Specifically, @Schema(description = "field", type = "integer", example = "22") is being displayed as:

"field": {
            "type": "string",
            "description": "field",
            "example": "22"
          }

where the previous version would show:

"field": {
            "type": "integer",
            "description": "field",
            "example": "22"
          }

To Reproduce
Steps to reproduce the behavior:
Set schema explicitly using @Schema annotation, check /v3/api-docs and see mismatch.

• What version of spring-boot you are using? 3.5.8
• What modules and versions of springdoc-openapi are you using? org.springdoc:springdoc-openapi-starter-webmvc-ui:2.8.14
• What is the actual and the expected result using OpenAPI Description (yml or json)?
  Actual:

"field": {
            "type": "string",
            "description": "field",
            "example": "22"
          }

Expected:

"field": {
            "type": "integer",
            "description": "field",
            "example": "22"
          }

• Provide with a sample code (HelloController) or Test that reproduces the problem

@RestController
public class HelloController {

    @GetMapping("/hello")
    public SampleResponse hello() {
        SampleResponse res = new SampleResponse();
        res.setField(true);
        res.setCount(22);
        res.setNote("ok");
        return res;
    }

    public static class SampleResponse {

        // Explicit override (expected: boolean), but in 2.8.14 becomes string in /v3/api-docs
        @Schema(description = "field", type = "boolean", example = "true")
        private Boolean field;

        // Control case: explicit integer (expected integer)
        @Schema(description = "count", type = "integer", example = "22")
        private Integer count;

        // Control case: inferred string (expected string)
        private String note;

        public Boolean getField() { return field; }
        public void setField(Boolean field) { this.field = field; }

        public Integer getCount() { return count; }
        public void setCount(Integer count) { this.count = count; }

        public String getNote() { return note; }
        public void setNote(String note) { this.note = note; }
    }
}

Expected behavior
Correctly set the type according to the explicit @Schema annotation

Most likely tied to the bump of swagger-core here. It is the component responsible for most of the Java-object to OpenApi-specification translation.

Could you state if you are exposing a 3.1 or 3.0 specification? If it is 3.1, I believe the correct field to use is types, so you could try to see if that adjusts the behavior.

I can verify it is a 3.0 specification. I understand it is not recommended to specify the version but a consuming client is currently reliant on that 3.0.

My attempt at reproducing the issue does not seem to yield the same results. Could you submit an example branch where you are able to reproduce the issue in this repository?
