 Description   

The web application can return a response page with empty content.
If this page is requested for the first time, it is correctly returned.
If this page is requested for the second time, there is no response and the web
application is not accessible any more. The Admin interface can still be accessed.
It seems that the cache fails when serving an empty file.

Happens on a vanilla installation of glassfish 3 and the following cache
settings in sun.web.xml:

<cache enabled="true" max-entries="4096" timeout-in-seconds="30">
<cache-mapping>
<servlet-name>dispatcher</servlet-name>
</cache-mapping>
</cache>

The problem also occurrs on v2.1.1
