Claus Ibsen commented on CAMEL-11506:
-------------------------------------
What JDK version do you use, maybe try to upgrade, as you end up using the HTTP
client from the JDK (according to stacktrace) and it may be better in newer
version.

> It would be really helpful if we'd had a method to specify a timeout or at
> least that a good timeout value is preset as default. (like 1 minute for
> instance)
> Tbh I am rather unsure if that can be fixed in Camel directly or if Ivy
> should be fixed. IMO before accessing a URI Ivy's BasicURLHandler should use
> the isReachable(url, timeout) to test if it makes sense at all to connect
> instead of using getURLInfo right away?
