# Springdoc v2.8.15 path matching build error with Spring Boot v3.4.4

## Description

### **Describe the bug**

Spring Boot version 3.4.4 application does not build/run with `springdoc-openapi-starter-webmvc-ui` version 2.8.15. It fails with the following error when running `mvn clean spring-boot:run`:

```
***************************
APPLICATION FAILED TO START
***************************

Description:

Invalid mapping pattern detected:
/swagger-ui/**/*swagger-initializer.js
           ^
No more pattern data allowed after {*...} or ** pattern element

Action:

Fix this pattern in your application or switch to the legacy parser implementation with 'spring.mvc.pathmatch.matching-strategy=ant_path_matcher'.
```

However, after downgrading to springdoc version 2.8.14, the application runs as expected (NOTE: setting the mentioned property to `ant_path_matcher` also doesn't work). This seems to be related to [#3145](/content/springdoc/springdoc-openapi/issues/3145/index.html)

### Sample application modules + versions

- Spring Boot version: **3.4.4**
- Java version: **17**
- Maven version: **3.8.1**
- Springdoc-openapi
  - module: **springdoc-openapi-starter-webmvc-ui**
  - broken version: **2.8.15**
  - working version: **2.8.14**

### Sample application code

`pom.xml`

```

      </plugin>
    </plugins>
  </build>
</project>
```

`App.java`

```
package com.demoapp.repro;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {
  public static void main(String[] args) {
    SpringApplication.run(App.class, args);
  }
}
```

`HelloController.java`

```
package com.demoapp.repro;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
  @GetMapping("/hello")
  public String hello() {
    return "Hello, World!";
  }
}
}
```

### **Steps to Reproduce**

1. Copy the above code into a demo folder (i.e. `{demoRoot}/pom.xml`, `{demoRoot}/src/main/java/App.java`, and `{demoRoot}/src/main/java/HelloController.java`)
2. Run the following terminal command `mvn clean spring-boot:run`
3. Check terminal output or navigate to [http://localhost:8080/swagger-ui/index.html](http://localhost:8080/swagger-ui/index.html)

To get a working version:

1. Change the package version in `pom.xml` to **2.8.14**
2. Run the same `mvn clean spring-boot:run` command in the terminal
3. Check terminal output or navigate to [http://localhost:8080/swagger-ui/index.html](http://localhost:8080/swagger-ui/index.html)

### **Expected behavior**

- Application builds and runs without maven build error
