UriComponentsBuilder.pathSegments(...) should drop empty segments [SPR-9077]

[spring-projects-issues]

Oliver Drotbohm opened SPR-9077 and commented

When handing empty segments into UriComponentsBuilder.pathSegments(...) double slashes are created which are semantically equivalent to a single slash. Thus, empty path segments can/should be dropped:

UriComponentsBuilder.pathSegment("", "foo", "", "bar");

Result: //foo//bar
Expected: /foo/bar
