NPE after >24 pause between deploys WF 35.0.1.Final

Hi!
We got a deploy NPE issue which happened on one of the servers, and just after the weekend or holidays

There is a cluster with 3 nodes, sticky sessions turned on

NPE is caused by a nullable last update time in the Session

Caused by: java.lang.NullPointerException: Cannot invoke "java.time.Instant.plus(java.time.temporal.TemporalAmount)" because the return value of "org.wildfly.clustering.server.expiration.ExpirationMetaData.getLastAccessTime()" is null at org.wildfly.clusteri...@5.0.4.Final//org.wildfly.clustering.server.infinispan.expiration.ExpirationMetaDataFunction.apply(ExpirationMetaDataFunction.java:23) at org.wildfly.clusteri...@5.0.4.Final//org.wildfly.clustering.server.infinispan.expiration.ExpirationMetaDataFunction.apply(ExpirationMetaDataFunction.java:18) at org.wildfly.clus...@5.0.4.Final//org.wildfly.clustering.server.scheduler.Scheduler$1.schedule(Scheduler.java:46) at org.wildfly.clus...@5.0.4.Final//org.wildfly.clustering.server.scheduler.Scheduler$ReferenceScheduler.schedule(Scheduler.java:121) at org.wildfly.clustering.se...@5.0.4.Final//org.wildfly.clustering.session.infinispan.embedded.SessionExpirationScheduler.schedule(SessionExpirationScheduler.java:95)

I've created a ticket about it https://issues.redhat.com/browse/WFLY-20617

Any advice is appreciated, thanks!
