SingletonProvider may be incorrectly initialized with RegistrySingletonProvider ------------------------------------------------------------------------------- Key: WFLY-9821 URL: https://issues.jboss.org/browse/WFLY-9821 Project: WildFly Issue Type: Bug Components: CDI / Weld Affects Versions: 11.0.0.Final Reporter: Martin Kouba Assignee: Martin Kouba Fix For: 12.0.0.CR1 If a non-CDI deployment (contains no beans.xml nor a bean with a bean defining annotation nor a session bean) attempts to access the CDI container using {{CDI.current()}} before {{TCCLSingletonService}} is started (and {{org.jboss.weld.bootstrap.api.SingletonProvider}} initialized with {{ModuleGroupSingletonProvider}}) then {{SingletonProvider}} is incorrectly initialized with the default impl ({{RegistrySingletonProvider}}). As a result, subsequent CDI deployments fail with {{java.lang.RuntimeException: SingletonProvider is already initialized...}}.
