Subject: [PATCH] Update oic_session.rb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Keycloak will encode the User info with url safe encoder using ‘-’ instead of ‘+’ and ‘_’ instead of ‘/’. When the base64encoded string contains '-' or '_' , orignal code will throw `500 JSON::ParserError`. This change will fix it.
