SLO issue with hostname.local type url (version 5.1.0)

[Catalin Dobrea]

Hi

I am using CAS 5.1.0-RC3 for some time, but I have seen now there's available the 5.1.0 version which should be more stable etc
So I've switched to 5.1.0. As a side effect SLO not working anymore.

First I have observed the following in the logs: 0 logout requests were processed (output from DefaultLogoutManager class)
Then I have set up some breakpoints and found out that I will never get a logout url since the validation of the logout url is failing

So in DefaultSingleLogoutServiceLogoutUrlBuilder#determineLogoutUrl  there is this following line:

UrlValidator.getInstance().isValid(singleLogoutService.getOriginalUrl()) ? new URL(singleLogoutService.getOriginalUrl()) : null;

Unfortunately, this will not see the following url https://my-desktop.local/uber-service as valid, I guess ..the presence of the .local as being the toplevel domain

Is there a way to bypass this ? Explanation: I need .local because we need to test our web app specifically on iPad and I have installed Bonjour on my laptop (running windows) in order to be able to access my dev machine on iPad by DNS/hostname.

Btw the UrlValidator comes from org.apache commons-validator version 1.6 . Was the version of this jar touched or smth ?

Thanks in advance for any suggestions.
