Uploading 7Mb file results in web/app server out of memory error (default Tomcat installation)

In my case I got an error from Tomcat when uploading 7MB zip file:

HTTP Status 500 -

type Exception report

description The server encountered an internal error () that prevented it from fulfilling this request.

javax.servlet.ServletException: Filter execution threw an exception
org.hippoecm.frontend.plugins.login.ConcurrentLoginFilter.doFilter(ConcurrentLoginFilter.java:54)

root cause

java.lang.OutOfMemoryError: Java heap space

Two suggestions:
CMS should make sure that we do not upload files that are too large or give a proper error message.
CMS should be able to handle 7Mb files in a default environment.
