Performance: WeldDeployment.getBeanDeploymentArchive method is synchronized --------------------------------------------------------------------------- Key: WFLY-6405 URL: https://issues.jboss.org/browse/WFLY-6405 Project: WildFly Issue Type: Bug Components: CDI / Weld, Class Loading Affects Versions: 10.0.0.Final Reporter: Panos Grigoropoulos Assignee: Stuart Douglas Fix For: 10.1.0.CR1, 10.1.0.Final (Wildfly 10.0.0.FINAL) During the performance test of my app (50 concurrent users with jmeter) I am running into the following issue: There are locked threads in the method WeldDeployment.getBeanDeploymentArchive(). Looking the code, this method is synchronized, so it makes sense. The question is, is this the expected behavior or this is a bug. In both cases is there any workaround to overcome this limitation?
