AbstractComponentRegistry.getComponent can return an incomplete component ------------------------------------------------------------------------- Key: ISPN-2876 URL: https://issues.jboss.org/browse/ISPN-2876 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Affects Versions: 5.2.2.Final Reporter: Dan Berindei Assignee: Mircea Markus Fix For: 6.0.0.Final AbstractComponentRegistry.getComponent doesn't have any locking, so it's possible for a thread to retrieve a component while another thread is injecting that component's dependencies. Normally this isn't a problem, because the global registry is locked during cache manager startup, and the cache registry is locked during cache startup. However, some global components are only created "on-demand", because a cache component depends on them, and this can happen if someone uses getComponent instead of getOrCreateComponent.
