"default" as default name for long-running-threads and short-running-threads leads to thread groups with the same name default-threads --------------------------------------------------------------------------------------------------------------------------------------- Key: WFCORE-1559 URL: https://issues.jboss.org/browse/WFCORE-1559 Project: WildFly Core Issue Type: Enhancement Components: Server Affects Versions: 2.1.0.Final Reporter: Martin Simka Assignee: Jason Greene Priority: Minor /subsystem=jca/workmanager=default/short-running-threads=default /subsystem=jca/workmanager=default/long-running-threads=default Thread group with name {{default-threads}} is created for both of these addresses. It's because thread group name is created from last element of resource's address + string {{-threads}}. [ThreadPoolManagementUtils.java#L166|https://github.com/wildfly/wildfly-co...] {code:java} params.name = pathAddress.getLastElement().getValue(); {code} [ThreadFactoryResolver.java#L149|https://github.com/wildfly/wildfly-core/b...] {code:java} protected String getThreadGroupName(String threadPoolName) { return threadPoolName + "-threads"; } {code} Thread groups for different resources shouldn't have the same name. Also such a general name {{default-threads}} could be confusing when debugging.
