Author: Guillaume Smet <guillaume.smet(a)gmail.com&gt; Date: 2018-07-19 (Thu, 19 Jul 2018) Changed paths: M hibernate-core/src/main/java/org/hibernate/mapping/Component.java M hibernate-core/src/test/java/org/hibernate/test/component/proxy/ComponentBasicProxyTest.java Log Message: ----------- HHH-12791 Cache the Component type to avoid generating one proxy per call While Javassist only generates one proxy as the name is stable, ByteBuddy uses random names and thus generates a new proxy for every call, leading to the generation of 18 different proxies for the other test of the test class. We can't do better than using a volatile/synchronized pattern as the Component is not fully initialized in the constructor. Maybe we could take the risk of admitting that the getType() method is called at least once before we pass the element to a multi-threaded environment but that's a bet I don't want to take alone. **NOTE:** This service been marked for deprecation: https://developer.github.com/changes/2018-04-25-github-services-deprecation/ Functionality will be removed from GitHub.com on January 31st, 2019.
