Wildfly 10.1.0 blocks calls to Singleton EJBs in PostConstruct -------------------------------------------------------------- Key: WFLY-7101 URL: https://issues.jboss.org/browse/WFLY-7101 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 10.1.0.Final Environment: Wildfly 10.1.0 running under Windows 10 with Java 1.8.0_91 Reporter: Dietrich Schmidt Assignee: Jason Greene Attachments: Verklemmung.zip Wildfly 8.2.0 and 10.0.0 work fine with a Singleton Bean, which has a @Postconstruct method and in this method several threads are created with the ManagedExecutorService. These threads call a method in another Singleton EJB, which has been injected. This call is blocked in Wildfly 10.1.0 until the Prostconstruct thread has ended. I assume that the behaviour of Wildfly 8.2.0 + 10.0.0 is correct and the behaviour of Wildfly 10.1.0 is a bug.
