> 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.
