Spring Filter ClassCastException when running project on Tomcat

I am getting following error when I try to run my project on Tomcat. It was working before but I updgraded jackson version to 1.9.13 from 1.9.7 and I was not able to run the project anymore after updating maven dependencies. I tried to downgrade Jackson to 1.9.7 but no chance.

SEVERE: Error filterStart

I have checked all answers related to this problem. They all say that I need to define scope as provided and I already have. Here is my servlet-api dependency definition.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

I can't find any servlet-api dependency under any of dependency in my pom.xml. Here is all my pom.xml.

I spent several hours on this problem but I got stuck. Even if I disable filtering, I am getting another class cast exception related to this servlet-api scope problem. But I can't find any servlet-api jar. Any help is highly appreciated.

Thanks in advance.
