WSO2 Identity Server claims no longer mapping 6.1.0

Question

This was working correctly in version 5.11.0. In my configuration I had a service provider setup to authenticate inbound requests using OAuth2 which was connected to a federated identity provider. The federated identity provider would authenticate using SAML2. When the SAML2 request is sent back the assertion would be sent to the /oauth2/token using the "urn:ietf:params:oauth:grant-type:saml2-bearer" grant type. The SAML2 assertion would contain a list of user attributes that would map to oidc claims. Now, in version 6.1.0, using the same process no longer works and the claims do not get mapped. I checked to make sure the mappings were setup as they were in 5.11.0.
