The release v0.0.3 of the  porcupine [see also screencast] of the concurrency utility for Java EE 7 is available in maven central:



<dependency>
	<groupId>com.airhacks</groupId>
	<artifactId>porcupine</artifactId>
	<version>0.0.3</version>
</dependency>



This version introduces two minor conveniency features:


A custom configuration could be created more conveniently, partially overriding the defaults.


import com.airhacks.porcupine.configuration.control.ExecutorConfigurator;
import com.airhacks.porcupine.execution.control.ExecutorConfiguration;
import javax.enterprise.inject.Specializes;

@Specializes
public class CustomExecutorConfigurator extends ExecutorConfigurator {

    @Override
    public ExecutorConfiguration forPipeline(String name) {
        if ("custom".equals(name)) {
            return new ExecutorConfiguration.Builder().
                    queueCapacity(1).
                    build();
        } else {
            return ExecutorConfiguration.defaultConfiguration();
        }
    }
}




For all statistic entities, the method toString was implemented for nicer debugging output: Rejection{statistics=Statistics{pipelineName=moviesThreadPool, remainingQueueCapacity=0, completedTaskCount=3, activeThreadCount=1, largestThreadPoolSize=1, currentThreadPoolSize=1, totalNumberOfTasks=9, maximumPoolSize=1, rejectedExecutionHandlerName=(...), rejectedTasks=1}, taskClass=(...)}



See you at Java EE Workshops at Munich Airport, Terminal 2 or Virtual Dedicated Workshops / consulting. porcupine is used and discussed during the microservices workshop.
