WARN on AbstractSAML2AttributeTranscoder

Cath Messner
We undergoing upgrade to 4.0.1 (from 3.4.7) -- on startup the following message appears,

eduPersonScopedAffiliation values are being generated (i.e. urn:oid:1.3.6.1.4.1.5923.1.1.1.9).

I'm still digesting TranscodingRuleConfiguration -- I'm not sure if it's related.

Could anyone guide on where to look to narrow down what is generating the WARN? Thanks.

I'd have to see the XML it's trying to decode. The code is complaining because there's apparently an AttributeValue in the XML but the decoding process didn't manage to pull anything out, as though it wasn't proper syntax or something. It's probably a bug but I reserve judgement.
