<p>
I've written a small JACC implementation that I've configured and used successfully in
Glassfish v2ur1. Good stuff! Works a treat!
</p>
<p>
But, here's the weird part, for some reason I get a NullPointerException in
com.sun.web.security.WebSecurityManager's checkPermission [b]unless[/b] I make a call
to the static method com.sun.enterprise.security.PermissionCacheFactory.resetCaches()
in the static block of my Policy implementation.
</p>
<p>
This method set the private member variable supportsReuse to true and my JACC implemetation
works fine.
</p>
<p>
I can't help but feel this is not doing things the right way.
</p>
<p>
Any ideas?
</p>
<p>
Here a partial stacktrace if I disable my "glassfish workaround":
