---------------------------------------------------------------
I am able to reproduced this. I see the problem is due to the hostname which is
considered as 127.0.0.1 in case of Java17 whereas for Java8 it is 192.168.1.2,
Due to which when it is trying to resolve the rackId in
'StaticMapping.resolve()' it is not getting value from nameToRackMap where it
contains value for '192.168.1.2'. Hence the default rack value is assigned.
CachedDNSToSwitchMapping.resolve is playing important role here.
Looking more into it.
