Running Liferay as a separate application context other than ROOT throws NullPointerExceptions.

Steps to reproduce:

1) Install Liferay 7 in stock Tomcat 8.0.32 following the steps here: https://dev.liferay.com/discover/deployment/-/knowledge_base/7-0/installing-liferay-on-tomcat-8 but using a different application context name instead of ROOT. For instance: CATALINA_HOME/webapps/my-context

2) Rename CATALINA_HOME/conf/Catalina/localhost/ROOT.xml to CATALINA_HOME/conf/Catalina/localhost/my-context.xml

3) Edit file renamed in the previous item to change the path attribute of <Context> to "/my-context"

4) Set portal.cxt and portal.proxy.path to /my-context in LIFERAY_HOME/portal-ext.properties (I believe porta.cxt is now obsolete)

5) Edit CATALINA_HOME/webapps/my-context/WEB-INF/web.xml:
Add new context-param
<context-param>
<param-name>root_path</param-name>
<param-value>/securescape</param-value>
</context-param>

and edit context-param below (change is marked in bold):

<context-param>
<param-name>osgi.http.endpoint</param-name>
<param-value>/securescape/o/</param-value>
</context-param>

After starting the portal, try to hit localhost:8080/my-context. It should throw this exception: https://gist.github.com/igorarouca/7b75147374855880f715360f92c8a3f7
