I get this also with this Jython script, so it’s not a Grade-only issue:

>>> from java.net import * 
>>> z = InetAddress.getAllByName("233.253.17.122")
>>> q = MulticastSocket(7912)                     
>>> q
java.net.MulticastSocket@3c88831
>>> z     
array(java.net.InetAddress, [/233.253.17.122])
>>> q.joinGroup(z[0])

This is FreeBSD bug #193246: Bug in IPv6 multicast join(), uncovered by Jenkins
 and can be worked around by adding -Djava.net.preferIPv4Stack=true to Java VM arguments.

…but I have some trouble adding -Djava.net.preferIPv4Stack=true… tried JAVA_OPTS, GRADLE_OPTS, as well as ./gradlew -Djava.net.preferIPv4Stack=true and listing in $HOME/.gradle/gradle.properties - nothing seems to work. Also when the daemon gets started it has those options not set (I tested with -no-daemon of course).
