> In short, there is a bug in ignite-spring-session-ext implementation.
> We store IgniteIndexedSessionRepository${{{}IgniteSession{}}} in the cache, but it’s an internal non-static class, having a reference to the parent [\{{{}IgniteIndexedSessionRepository{}}}] indirectly.
> Hence, during the serialization Ignite also writes {{{}name=this$0, type=Object, fieldId=0xCBDD23AA (-874699862){}}}, which is the reference to {{{}IgniteIndexedSessionRepository{}}}. That leads to the following issues:
>  * we are serializing and saving internal utility data, like{{{{}} Ignite ignite{}}}, {{private IndexResolver<Session> indexResolver}} etc
>  * one of the IgniteIndexedSessionRepository’s fields is IgniteCache itself - {{IgniteCache<String, IgniteSession> sessions}} that basically keeps every session so far leading to a StackOverflow error after some time.
