Hi,

instead of discussing ant versions I want to draw your attention to
#560044, #560056 and similar bug reports. I think that is a much worse
problem and we need a solution.

Cheers,
Torsten

thanks to the overwhelming response I have looked at this issue by
myself. The fix is in openjdk-6 version 6b18~pre1-3 now. Please check
your java apps if it really fixes the problem.

Cheers,
Torsten

For freecol, it does not.

For the record, after the switch to net.ipv6.bindv6only, I had to add
-Djava.net.preferIPv4Stack=true for freecol to run in local mode (with a
localhost server, as far as I can tell).

I wonder if the problem is within freecol or within java. Freecol
listens in IPV6 but seems to connect as IP4...

I'll have a closer look into the (freecol) code.

We've done the same workaround for zekr package.

I tried to see how other distributions are handling this issue regarding
the Sun JDK but I haven't found anything...
It is going to be a very boring issue in Squeeze if Sun does not move
here ...

specifying -Djava.net.preferIPv4Stack=true will switch off IPv6
completely. This is not a good idea.

I'll have a look at the freecol packages.

Cheer,s

Don't bother:

freecol fails, because it spawns a server on "localhost", but it
connects using 127.0.0.1.

What I think is happening is that localhost is IPv6 by default (why ?)
so freecol fails when it later connects to 127.0.0.1.

Is that a bug in openjdk (ie fails to listen on both IPv6 and IPv4, or
takes localhost as IPv6 only) or freecol ? (where it should call both as
localhost ?).

I hope it makes it more clear.

Cheers,

Vincent

Yes that is the problem. Replacing 127.0.0.1 with localhost should be
the correct fix.

It listens on [::]:3541 and that is IPv6 only if net.ipv6.bindv6only=1.

freecol

OK, thanks.

Upstream is about to release a new version (fixing major usability
bugs for the 0.9 series, which I haven't packaged yet because of these);
I'll see if the problem still occurs, and I'll fix it if needs be.

Cheers,

Vincent
