UriComponents uri1 = UriComponentsBuilder.fromUriString( "" ).build().normalize();
UriComponents uri2 = UriComponentsBuilder.fromUriString( "" ).build();
assert !uri1.equals( uri2 );


	at org.springframework.web.util.HierarchicalUriComponents$FullPathComponent.equals(
	at org.springframework.web.util.HierarchicalUriComponents.equals(

UriComponentsBuilder.fromUriString( "" ).build().normalize().getPathSegments()
