Prior to this commit, resolving resources from webjars using the `WebJarAssetLocator.getFullPath` could lead to multiple candidates, since this method is trying to find *any* resource matching that path under the given webjar location. This commit replaces that call with `WebJarAssetLocator.getFullPathExact`, which avoids those multiple matches and only resolves resources if the given path is exact. Issue: SPR-15526
