1. Simply run the Showcase using MyFaces 4.0
2. Execute `curl` or `PowerShell` to hit the site with an invalid Content-Type.
{code:powershell}
$response = Invoke-WebRequest -Uri
"http://localhost:8080/showcase/ui/ajax/process.xhtml"; -Method GET -Headers @{
Accept = "text/plain" } -AllowInsecureRedirect
{code}
3. Because it gets the error it tries to redirect to `/showcase/error.xhtml`
using `externalContext.redirect(url);`. This however just generates the same
error in MyFaces in an infinite loop.
