             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 at 7a988e48' for capability 'BPM'
{noformat}

Which is likely caused by ServiceLoader returning incorrect output in some race condition.
