Issue Type: Bug Affects Versions: 3.4.0 Assignee: Henri Mikkonen ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A1614c4a5-c89e-4edc-9421-990bd6ea85fd ) Created: 16/May/23 6:21 AM Priority: Trivial Reporter: Henri Mikkonen ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A1614c4a5-c89e-4edc-9421-990bd6ea85fd )

The new *java-idp-plugin-oidc-config* plugin contains a wrong claimsValidator reference for AbstractOIDCSSOProfile, which is inherited by *OIDC.SSO* and *OAUTH2*.Token profiles. The referenced bean *shibboleth.oidc.DefaultJWTClaimsValidator* is not defined neither by common-config nor OP by default.

The corresponding MDDriven profiles (defined in the OP, to in the common config) points to a bean DefaultJWTClaimsValidator , which is defined in the OP’s relying party configuration.

The wrong reference leads into failed client JWT authentication in the token endpoint:
