Problem with DateTimeFormatter not serializable

[joaomoraski]

I am trying to implement Hazelcast for session replication in version 5.3.2 on Tomcat.

When I run my system, at the time of retrieving the session, it returns an error saying that it was not possible to serialize the DateTimeFormatter. I tried changing the class variable to a function or something similar in various places, but nothing had any effect.

After researching a bit, I found out that DateTimeFormatter is not serializable by Java's own decision. So, I would like to know if anyone has had a similar issue or if there is a known solution to address this problem.
