I get an Error using multiple Extensions:

Error 500 java.lang.AbstractMethodError: Receiver class org.wiremock.RandomHelper does not define or inherit
        an implementation of the resolved method 'abstract java.lang.Object apply(java.lang.Object,
        wiremock.com.github.jknack.handlebars.Options)' of interface
        wiremock.com.github.jknack.handlebars.Helper.

Reproduction steps

@SpringBootApplication
public class Demo4Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo4Application.class, args);
        var store = new CaffeineStore();
        WireMockServer server = new WireMockServer(
                options()
                        .port(1234)
                        .templatingEnabled(true)
                        .globalTemplating(true)
                        .extensions(new StateExtension(store))
                        .extensions(new RandomExtension())
                        .usingFilesUnderDirectory("src/main/resources")
        );
        server.start();
    }
}

The mapping:

{
  "mappings": [
    {
      "request": {
        "urlPathPattern": "/store",
        "method": "POST"
      },
      "response": {
        "status": 200,
        "body": "{{ random 'BojackHorseman.quotes'}}"
      },
      "serveEventListeners": [
        {
          "name": "recordState",
          "parameters": {
            "state": {
              "stored": "{{request.body}}"
            },
            "context": "profile"
          }
        }
      ]
    },
    {
      "request": {
        "urlPathPattern": "/stored",
        "method": "GET"
      },
      "response": {
        "body": "stored {{state context='profile' property='stored' default='nothing here'}} + a random value"

      }
    }
  ]
}

The gradle File

plugins {
    java
    id("org.springframework.boot") version "3.4.0"
    id("io.spring.dependency-management") version "1.1.6"
}

@zyberzebra did you resolve this? I get the error with a single extension

Not really. I stopped investigating at some point and just removed the faker extension.

Check if you're not using wiremock-standalone, and if so, use wiremock-faker-extension-standalone.
I was having the same problem here, and later realized that this was the problem.
