Logging in via oauth2 using redis session throws jackson error

Describe the bug
When I attempt to login via oauth 2 using redis sessions I get this jackson error

org.springframework.data.redis.serializer.SerializationException: Could not read JSON:Could not resolve type id 'java.net.URL' as a subtype of `java.lang.Object`: Configured `PolymorphicTypeValidator` (of type `tools.jackson.databind.jsontype.BasicPolymorphicTypeValidator`) denied resolution
 at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); byte offset: #1988] (through reference chain: org.springframework.security.core.context.SecurityContextImpl["authentication"]->org.springframework.security.oauth2.client.authentication.OAuth2AuthenticationToken["principal"]->org.springframework.security.oauth2.core.oidc.user.DefaultOidcUser["authorities"]->java.util.HashSet[0]->org.springframework.security.oauth2.core.oidc.user.OidcUserAuthority["idToken"]->org.springframework.security.oauth2.core.oidc.OidcIdToken["claims"]->java.util.LinkedHashMap["iss"])

the error location of the json in redis appears to be here

          "iss": [
            "java.net.URL",
            "https://accounts.google.com"
          ],

I am using the documentation code for 4.0.1-SNAPSHOT

Sample

Here is a link to the sample. To set it up add your oauth2 details to application.yml, start up spring boot and attempt to login

Start with the Spring Session Redis JSON serialization documentation for 4.0.1-SNAPSHOT and the sample project's application.yml. Reproduce the OAuth2 login with Redis sessions, then inspect how the OIDC issuer claim is serialized and read. Done means the login completes without the Jackson error and the session remains readable from Redis.
