Oauth2.tokeninfo IllegalArgumentException: key error

When attempting to call Oauth2.tokeninfo() with an access token from a service key, an exception is sometimes thrown, with no clear pattern.

Code:

    private val transport = GoogleNetHttpTransport.newTrustedTransport()
    private val jsonFactory = JacksonFactory.getDefaultInstance()
...
        val credential = GoogleCredential.fromStream(privateKeyStream)
                .createScoped(Collections.singleton("https://www.googleapis.com/auth/userinfo.email"))
        val oauth = Oauth2.Builder(transport, jsonFactory, credential)
                .setApplicationName("SomeAppName")
                .build()
        val tokenInfo = oauth.tokeninfo()
                .setAccessToken(credential.accessToken)
                // This is throwing the exception
                .execute()

Much of the time, execute returns properly and tokenInfo contains the requested data. Sometimes, however, the following exception is thrown (internal package names have been replaced with foo.bar):

Note that while this stack trace was thrown from a test case, the same behavior is seen when running it “normally”

1.25.0 is released!

@chingor13 Im not sure this is actually fixed. I’ve upgraded to https://mvnrepository.com/artifact/com.google.apis/google-api-services-oauth2/v2-rev141-1.25.0 and now I’m getting a different, but similar, error:

Its pretty much the same thing; it randomly throws this error, but retrying once or twice always ends up working.
