Hi,
Copied from the bug https://bugs.openjdk.java.net/browse/JDK-8222562:
Some of the networking code tries to support dual socket support.
However, it doesn't work with IPv6 only systems.
setsockopt(fd, IPPROTO_IPV6, IPV6_V6ONLY, 0) returns a failure with
errno EAFNOSUPPORT, and then the networking code bails. It should not
bail when it sees that trying to set IPV6_V6ONLY fails.
I assume that you are on Linux, right? If so, have you compiled the
Kernel without IPv4 support? How have you configured your system without
IPv4 support?
I'm curious as I would like to try something similar, as well as on
other platforms, macOS, etc.
