Test case:

UriComponents uri1 = UriComponentsBuilder.fromUriString( "http://test.com" ).build().normalize();
UriComponents uri2 = UriComponentsBuilder.fromUriString( "http://test.com/" ).build();
assert !uri1.equals( uri2 );

Throws:

java.lang.NullPointerException
	at org.springframework.web.util.HierarchicalUriComponents$FullPathComponent.equals(HierarchicalUriComponents.java:700)
	at org.springframework.web.util.HierarchicalUriComponents.equals(HierarchicalUriComponents.java:464)
...

Also, this code throws NullPointerException:

UriComponentsBuilder.fromUriString( "http://test.com" ).build().normalize().getPathSegments()

This seems to work fine in 5.0.x; I'll check 4.3.x tomorrow.
