Thomas Vandahl commented on JCS-133:
------------------------------------
An alternative would be to try to resolve the address and see if it is a IPv6
address. That, however, might trigger DNS timeouts (30 sec), which should be
avoided IMO. I'm fine with the fix.
> RemoteUtils.getNamingURL does not handle IPv6 numeric addresses properly

> Key: JCS-133
> URL: https://issues.apache.org/jira/browse/JCS-133
> Project: Commons JCS
> Issue Type: Bug
> Reporter: Sebb
> Fix For: jcs-2.0.0
>
>
> The RemoteUtils.getNamingURL method does the following concatenation to
> produce the result:
> "//" + registryHost + ":" + registryPort + "/" + serviceName;
> This works fine for host names and IPv4, but does not work for literal IPv6
> addresses which have to be enclosed in [ and ]
> A crude way to fix this would be to look for ":" in the registryHost string.
> If present, the zone index identifier (%2 or %eth0) needs to be encoded
> because the % is special.
