Change "Issue can't be viewed" page via custom plugin

Vasil'ev Nickolay

Is there any way to change the "Issue can't be viewed" page via custom plugin? I want to add simple link on this page or directly redirect to another page. 
There was some kind of solution for this problem, but it crashes the JIRA. 

Jira versoin: 7.5.3#75008 (server).

The one way to change "Issue can't be viewed" page is to implement custom servlet-filter plugin. Credits goes to @Alexey Matveev for an original idea.

I've come with next <servlet-filter> declaration:

 <servlet-filter name="My Servlet Filter" i18n-name-key="my-servlet-filter.name" key="my-servlet-filter" class="ru.temp.servlet.filter.MyServletFilter" location="before-decoration" weight="100">
 <description key="my-servlet-filter.description">The My Servlet Filter Plugin</description>
 <url-pattern>/browse/*</url-pattern>
 </servlet-filter>

The most important things in this declaration is:

1. location = "before-decoration". Default "before-dispatch" location is not suitable, because filter is never triggered that way - as mentioned in problems here and here, some URL's just can't be intercepted with custom servlet filter with this type of location. "before-login" and "after-encoding" is too early (no content in response can't be found yet).

1. url-pattern: /browse/* . I'm not sure on this one, but it seems there's no special inner path for an "Issue can't be viewed" error page. With this pattern filter is triggered on any issue page, even found one. Additional research may be appropriate.

Also, you may find these links useful:

1. Example of how to replace content in servlet filter;
2. How to set up encoding when output resulting page:

   response.setCharacterEncoding(response.getCharacterEncoding()); // You can preserve original response encoding
   response.getWriter().write(out);
