java.net.UnknownHostException InetAddress.getAllByName with many A-Records










1















I am getting a UnkonwHostException if I try to resolve a DNS Name which return more that 20 A Records.



To reproduce this, create a DNS Record with 20 A-Records and try to get it via:



try 
InetAddress var3 = InetAddress.getAllByName("manyrecords.and.longname.example.org");
catch (Exception ex)
System.out.println(ex.getMessage());



Reducing the DNS records to 5 for the subdomain, the query works again.
Tested with



openjdk version "10.0.2" 2018-07-17



openJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2)



OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2, mixed mode)



On windows it seems to work.
