In JcrAssetProvider.getAsset(String assetIdentifier) the stacktrace is logged on RepositoryException. That means the stacktrace is logged also in case, when the asset has not been found (e.g. has not been activated yet, but the page pointing to it yes). This causes quite high log-pollution in case that - for any reason - an non-existent asset is referenced from a frequently visited page.

It would be better if just the error message is logged in case of ItemNotFoundException, and stacktrace only in case of other RepositoryException.
