UDPSocket.new(Socket::AF_INET6) throws exception (JRuby 9.1.14.0) #4869
Description
Environment
Provide at least:
- JRuby version: 9.1.14.0
- Operating system and platform (e.g.

The example reproduction works correctly in JRuby 9.1.13.0
Expected Behavior
- Describe your expectation of how JRuby should behave, perhaps by showing how CRuby/MRI behaves.
