ResourceUrlEncodingFilter versioning breaks when URL contains fragment [SPR-17535]

[spring-projects-issues]

Ondřej Kraus opened SPR-17535 and commented

resolveUrlPath in ResourceUrlEncodingRequestWrapper in ResourceUrlEncodingFilter checks for query string, but not for fragment. This breaks versioning when URLs with fragment are used (tested with Thymeleaf):

th:src="@{/assets/images/icons/sprite.svg#face1}"

does not add version. Replacing getQueryParamsIndex with something that checks for both question mark and hash mark fixes it.

@rstoyanchev We are running into the same issue with 4.3.x, is there any chance to backport the fix?
