An alternative way to reproduce:
Skip step 1. and replace step 4. with:
- Touch webapps\examples\WEB-INF\web.xml
- Wait several seconds, until a success message is logged on the console
Reloading Context with name [/examples] is completed

The second sentence is missing more than just the timestamp.
The first part of it is missing as well. It had to be
[[[
To get the current time in ms by including the output of another JSP:
1408803609298 :-)
]]]
The source code of include.jsp page is essentially the following:
[[[
<%@ page buffer="5kb" autoFlush="false" %>
<p>In place evaluation of another JSP which gives you the current time:
<%@ include file="foo.jsp" %>
<p> <jsp:include page="foo.html" flush="true"/> by including the output of
another JSP:
<jsp:include page="foo.jsp" flush="true"/>
:-)
]]]
Thus both <jsp:include page="foo.html"> and <jsp:include page="foo.jsp"> are
failing.
I wonder why it silently skips the failed pages. I expected it to produce an
exception after the first failed include and abort the response.
The generated Java code for include.jsp does
[[[
out.write("<p> ");
org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response,
"foo.html", out, true);
out.write(" by including the output of another JSP:\r\n");
]]]
and the JspRuntimeLibrary.include() method just calls
RequestDispatcher.include(). Neither of them does any try/catch wrapping.
Why isn't javax.servlet.UnavailableException being thrown by RequestDispatcher?
