Marek Schmidt created DROOLS-1122: ------------------------------------- Summary: KieServicesClientImpl init not thread-safe Key: DROOLS-1122 URL: https://issues.jboss.org/browse/DROOLS-1122 Project: Drools Issue Type: Bug Components: kie server Reporter: Marek Schmidt Assignee: Edson Tirelli Creating separate clients via KieServicesFactory.newKieServicesClient in separate threads sometimes fails due to unsafe use of ServiceLoader (which by itself is not safe to use from separate threads per https://docs.oracle.com/javase/8/docs/api/java/util/ServiceLoader.html ) in droolsjbpm-integration/kie-server-parent/kie-server-remote/kie-server-client/src/main/java/org/kie/server/client/impl/KieServicesClientImpl.java The following can be seen in the logs of the failed threads {noformat} No builder found for 'BPM' capability {noformat} instead of the normal {noformat} Builder 'org.kie.server.client.helper.JBPMServicesClientBuilder@7a988e48' for capability 'BPM' {noformat} Which is likely caused by ServiceLoader returning incorrect output in some race condition. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
