Default Concurrency strategy for Query Cache in Hibernate using ECache <p>I was wondering about the default concurrency strategy for the Query level caching in Hibernate if we do not provide it explicitly. I have gone through the link <a href="https://docs.jboss.org/hibernate/orm/4.0/manual/en-US/html/performance.html#performance-cache" rel="nofollow">https://docs.jboss.org/hibernate/orm/4.0/manual/en-US/html/performance.html#performance-cache</a> but unable to find the exact solution. Any help? Thanks.</p>
