This is usually caused by not having a ipv6 network, and is fixable with this: -Djava.net.preferIPv4Stack=true
However I get this problem on Badlion and I have no way of adding this argument, is there any other fix for
java.lang.IllegalStateException: failed to create a child event loop?
and for Badlion?

Also This only happens on 1.16.3 (that i know of)
