Invalid Google OAuth2 Token?

I have a valid OAuth2 token that Google accepts, but GoogleIdTokenVerifier cannot even parse it.

Icon ya29.1.AADtN_XcjzHgauKetBvrbgHImGFg1pjiHRQAKHyTglBDjEZsTPUMQJ5p-xAKtk955_4r6MdnTe3HZ08(not worried, it has already expired).

It got on Android using

accountManager.blockingGetAuthToken(account, "oauth2:https://www.googleapis.com/auth/userinfo.email", true);

When I call https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=... I get a reasonable result, for example

{
  "issued_to": "34951113407.apps.googleusercontent.com",
  "audience": "34951113407.apps.googleusercontent.com",
  "scope": "https://www.googleapis.com/auth/userinfo.email",
  "expires_in": 3175,
  "email": "me@gmail.com",
  "verified_email": true,
  "access_type": "offline"
}

Therefore, it must be a valid token. But when I call

new GoogleIdTokenVerifier(new UrlFetchTransport(), JacksonFactory.getDefaultInstance())
    .verify(authToken)

It gives me

com.fasterxml.jackson.core.JsonParseException: Unexpected character ('É' (code 201)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

Debugging JsonWebSignature it seems that the token payload is equal 1.

• Android 4.4.2
• com.google.http client: google-http client-jackson2: 1.17.0-gs
• com.fasterxml.jackson.core: jackson-core: 2.3.0 ( 2.1.3 google-http-client-jackson) GsonFactory, , JsonWebSignature.parse().
