I am seeing NPEs after reloading a web application with a custom
<error-page>. Just downloaded the sample.war, added the following
block in web.xml and thus reloaded the web application:
<error-page>
<location>/404.jsp</location>
</error-page>
Accessing a nonexisting page now results in NPE instead of error page
being shown.
After tomcat restart the error-page is shown, until the next reload of
the application:
