Solution: exclude the servlet api jar. Verify that you don't have the servlet api jar in your maven dependencies.

Example:

Code Block

<dependency>
	<groupId>info.magnolia</groupId>
	<artifactId>magnolia-empty-webapp</artifactId>
	<version>4.0.1</version>
	<type>pom</type>
	<exclusions>
		<exclusion>
		        <groupId>javax.servlet</groupId>
		        <artifactId>servlet-api</artifactId>
		</exclusion>
	</exclusions>
</dependency>
