Description

Been seeing the error below in the logs. Strangely, I've not been able to catch the exception in a debugger, but was able to isolate it to the definition of the web-app with version 3.0. The error disapears when you change the definition from

<web-app version="3.0">

to this:

<web-app version="3.0"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

I only tested on 15.12 and Trunk, but it probably affects any release running Tomcat 7.0.48 or higher. Here is the error:
