hi,
disabling Second level cache in Hibernate solved this issue:
jpaPropertyMap.put("hibernate.cache.region.factory_class","com.hazelcast.hibernate.HazelcastCacheRegionFactory"); jpaPropertyMap.put("hibernate.cache.use_second_level_cache", "false"); jpaPropertyMap.put("hibernate.cache.use_query_cache", "false");
Now it is just never enters into SimpleTimestamper.java.
