Checksum archetype-catalog.xml invalid

The current archetype-catalog.xml deployed at http://maven.onehippo.com/maven2 has invalid checksums: neither md5 nor sha1 match.

This normally wouldn't be an issue for me, however, trying to proxy it through my artifactory repository I get:
" Rejected artifact download request: Checksum policy 'GEN_IF_ABSENT' rejected the artifact 'archetype-catalog.xml'. Checksums info: [ChecksumInfo

{type=MD5, original='da82f071c0ef680112b1cbdf3bf11c72', actual='8f5e9e868cd7d513bfd91f5aa355b7d9'}

, ChecksumInfo
