PathMatchingResourcePatternResolver should not re-resolve root URLs [SPR-14202]

[spring-projects-issues]

Juergen Hoeller opened SPR-14202 and commented

PathMatchingResourcePatternResolver calls Resource.getURL() on root resources several times. For ClassPathResource, this leads to re-resolution of ClassLoader.getResource which can be expensive. Initially resolving each root resource into a UrlResource, like we do for Equinox bundles already, should help here.
