NPE occurs when outputting an OpenAPI document since 2.5.0

[footaku]

NPE occurs when outputting an OpenAPI document in a project using springdoc-openapi 2.5.0.
It appears to occur only when certain annotations are included.
Specifically controller class with @Header annotation include @Schema attribute set.

    @Operation(
        // .....
        responses = {
            @ApiResponse(
                responseCode = "201",
                description = "201 (Created)",
                headers = {
                    @Header(
                        name = HttpHeaders.LOCATION,
                        description = "Sample endpoint",
                        schema = @Schema(implementation = URI.class) // include this.
                    )
                })
        }
        // ....
    )
    @GetMapping
    public String foo(){....}

To Reproduce
Steps to reproduce the behavior:

1. clone https://github.com/footaku/minimum-springdoc-npe
2. ./gradlew bootRun
3. curl -v "http://localhost:8080/v3/api-docs"

• What version of spring-boot you are using?
  • Spring Boot 3.2.4
• What modules and versions of springdoc-openapi are you using?
  • springdoc-openapi 2.5.0
• What is the actual and the expected result using OpenAPI Description (yml or json)?
  • JSON
• Provide with a sample code (HelloController) or Test that reproduces the problem
  • minimun sample: https://github.com/footaku/minimum-springdoc-npe

Expected behavior
NPE does not happen, can get JSON response.

Additional context
Swagger-core have been added getHeader overload methods into AnnotationsUtils.
This change seems to have been made between 2.2.20 and 2.2.21.
swagger-api/swagger-core@v2.2.20...v2.2.21

Around here that is added.

If we do not pass components, it will be thrown NPE here.
