I guess I should just use

Tnx to gregor for mentioning it.

This one is nearly useless.
With openjdk-1.7, I had to add printf into libc/network/getaddrinfo.c, to
figure out that something DNS related is problem.
Initially, I thought getaddrinfo() is problem - but that one fails at
https://github.com/cloudius-systems/osv/blob/master/libc/network/getaddrinfo.c#L197
,
so it returns a nullprt for res, which is a valid error.
After "manually" replacing openjdk with files from fedora 25, rebuild, etc.:

Now, java app shows error message, than both app and OSv exit nicely.
This is desired behavior I wish for.
On our openstack, I could get app up by ensuring that "dig host-10-32-3-20"
returns the VM IP.
The easiest solution for me is to just update openjdk to 1.8.0 from FC25.
But could that break some other java apps?
Alternative could be to have build time option to select openjdk 1.7 or 1.8.
