[jboss-jira] [JBoss JIRA] (DROOLS-1381) ConcurrentModificationException in ServiceLoader in org.kie.server.services.impl.security.JACCIdentityProvider.getNameFromAdapter

Marek Schmidt created DROOLS-1381: ------------------------------------- Summary: ConcurrentModificationException in ServiceLoader in org.kie.server.services.impl.security.JACCIdentityProvider.getNameFromAdapter Key: DROOLS-1381 URL: https://issues.jboss.org/browse/DROOLS-1381 Project: Drools Issue Type: Bug Components: kie server Affects Versions: 6.4.0.Final Reporter: Marek Schmidt Assignee: Edson Tirelli Spotted a ConcurrentModificationException just after startup with multiple clients starting processes concurrently. Seems the problem is unsynchronized access to the service loader in org.kie.server.services.impl.security.JACCIdentityProvider.getNameFromAdapter , so it may only occur after startup (e.g. when the node joins a busy cluster) {noformat} 18:03:52,495 WARN [org.drools.persistence.SingleSessionCommandService] (default-threads - 40) Could not commit session: java.util.ConcurrentModificationException
