protected static class QualifiedHostResolver implements HostResolver {
private List<String> searchDomains;
{
ResolverConfig resolverConfig = ResolverConfig.getCurrentConfig();
searchDomains = new ArrayList<>();
for (Name name : resolverConfig.searchPath()) {
searchDomains.add(name.toString());
}
}
{code}
