---------------------------------

Verrrrry interesting; I can think of all sorts of mayhem to cause with this.

Nice analysis.

> I call an action and expect to be redirected to another action BUT instead I get java.lang.NoSuchMethodException.
In my example Spring is in charge of constructing my Action object and I have a naive object
that returns a random String. It turns out that this random string is being somehow mistaken
by the action name, so I get something like java.lang.NoSuchMethodException: test.action.Test.TSldxhPcLq().
> I've made a simple project that is very simple to test.
> In the following example you can call "redirect" action and see the bug. I have a small
zip with this test project but I'm not finding any upload button.
