Description

Blocker: Specification violation resulting in RuntimeException

Dear Apache Contributors,

Recently I authored a pull request for OpenLiberty, which was then created by https://github.com/WhiteCat22.

 

Original issue:
https://github.com/OpenLiberty/open-liberty/issues/8863

 

Original PR:
https://github.com/OpenLiberty/open-liberty/pull/8956

Description

If a server returns HTTP link headers, it may do so with responding multiple link headers, or just one link header with comma separated fields.

CXF only  recognizes multiple link headers. If only one link header with multiple values was supplied, it will throw an unexpected RuntimeException: 

java.lang.IllegalArgumentException: Illegal character in query at index n: (Link header here)
Caused by: java.net.URISyntaxException: Illegal character in query at index

Examples

Working Response:

HTTP/1.1
Link: <http://localhost/api/endpoint?offset=0&sysparm_limit=5>;rel="first"
Link: <http://localhost/api/endpoint?offset=5&sysparm_limit=5>;rel="next"
Link: <http://localhost/api/endpoint?offset=45&sysparm_limit=5>;rel="last"

Not working response:

HTTP/1.1
Link: <http://localhost/api/endpoint?offset=0&sysparm_limit=5>;rel="first",<http://localhost/api/endpoint?offset=5&sysparm_limit=5>;rel="next",<http://localhost/api/endpoint?offset=45&sysparm_limit=5>;rel="last"

That should have worked, though.
