Could not open ServletContext resource [/<NONE>] when upgrade spring-boot-actuator 1.2.5.RELEASE

Question

I am using spring-boot-actuator dependency with version 1.1.2 with non spring boot application, now I want to upgrade to version 1.2.5.RELEASE to use the default chipped health endpoint in my application.

When I upgrade to 1.2.5.RELEASE the application fails to start up with error

 Could not open ServletContext resource [/<NONE>] 

I can see the configurationlocation is being set as NONE in AbstractRefreshableConfigApplicationContext so in the XmlBeanDefinitionReader it fails with this error.

Any help is appreciated.

here is the full stack trace:

The problem was when upgrading to spring-boot-actuator 1.2.5.RELEASE, for some reason the "contextConfigLocation" was removed so all I neded to do is to specify the contextConfiguration in my web.xml which is by default /WEB-INF/applicationContext.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
