Just on this topic.  JEP 418 [1] added the SPI that is needed to deploy 
an alternative resolver. Two prototype provider implementations exist, 
one based on JNDI DNS, the other uses the Netty name resolver. It would 
be a nice project for someone to run with one of those so that there is 
an alternative resolver available to deploy with server applications 
using virtual threads that do a lot of reserve DNS lookups.
