I used the dependencies from the 6.2SP1 on an AEM application which used javax.servlet.jsp.PageContext. We saw runtime issues and had to change the JSP and Servlet dependencies from:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.4</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.apache.felix.http.servlet-api</artifactId>
<version>1.1.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.scripting.jsp</artifactId>
<version>2.1.8</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.api</artifactId>
<version>2.11.0</version>
<scope>provided</scope>
</dependency>
