SpringBootTest failing with 'IllegalStateException - No ServletContext set'

Question

I have a pretty simple @SpringBootTest :

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = {...})
public class MyApplicationTest {

    @Test
    public void anyTest() { ... }
}

It was working as expected until we've added @EnableSchedulerLock (from Shedlock) on the MyApplication.java file.

Since, we're experiencing this issue :

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'resourceHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: No ServletContext set
    at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:185)
    at org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:582)
    ... 46 common frames omitted
Caused by: java.lang.IllegalStateException: No ServletContext set
    at org.springframework.util.Assert.state(Assert.java:73)
    at org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport.resourceHandlerMapping(WebMvcConfigurationSupport.java:483)

This happends when Spring tries to instanciate its resourceHandlerMapping :

@Bean
public HandlerMapping resourceHandlerMapping() {
    Assert.state(this.applicationContext != null, "No ApplicationContext set");
    Assert.state(this.servletContext != null, "No ServletContext set");
    ...

It's like this @Bean is created before the setServletContext (from WebMvcConfigurationSupport) is called.

As mentioned by Lukas, this error has been fixed in the latest version of Shedlock.

Upgrading Shedlock's version from 2.2.0 to 2.5.0 fixes the issue.
