seda not blocking when full

Hi,

I'm am using a producer template to send to a seda endpoint and it's not
blocking when full. Is there something wrong with my configuration? Using
v2.12.1.

<bean id="fileProcessor" class="FileProcessor">
<property name="workQueueEndpoint" ref="workQueue"></property>
<property name="producerTemplate" ref="producerTemplate"></property>
</bean>

<bean id="dataProcessor" class="DataProcessor"></bean>

<camel:camelContext id="test">

<camel:template id="producerTemplate" />

<camel:endpoint id="workQueue"
uri="seda:workQueue?size=2橪;blockWhenFull=true橪;concurrentConsumers=2橪;timeout=0"
/>

<camel:route>
<camel:from uri="file://c:/dvw/stream?delay=6666"></camel:from>
<camel:process ref="fileProcessor"></camel:process>
</camel:route>

<camel:route>
<camel:from ref="workQueue"></camel:from>
<camel:process ref="dataProcessor"></camel:process>
</camel:route>

</camel:camelContext>

public class FileProcessor implements Processor {

private static final Logger logger = Logger.getLogger(FileProcessor.class);

private Endpoint workQueueEndpoint;
private ProducerTemplate producerTemplate;

@Override
public void process(Exchange exchange) throws Exception {
FileReader fileReader = new
FileReader(exchange.getIn().getBody(File.class));
BufferedReader bufferedReader = new BufferedReader(fileReader);
Queue<Future;Object>> futures = new LinkedList<Future;Object>>();

for (String line = bufferedReader.readLine(); line != null; line =
bufferedReader.readLine()) {
logger.info("Sending " + line);

futures.add(this.getProducerTemplate().asyncRequestBody(this.getWorkQueueEndpoint(),
line));
logger.info("Sent " + line);

while (futures.size() > 0) {
Object o = futures.poll().get();
logger.info("Result for " + o);

bufferedReader.close();

public Endpoint getWorkQueueEndpoint() {
return workQueueEndpoint;

public void setWorkQueueEndpoint(Endpoint workQueueEndpoint) {
this.workQueueEndpoint = workQueueEndpoint;

public ProducerTemplate getProducerTemplate() {
return producerTemplate;

public void setProducerTemplate(ProducerTemplate producerTemplate) {
this.producerTemplate = producerTemplate;

public class DataProcessor implements Processor {

private static final Logger logger = Logger.getLogger(DataProcessor.class);

@Override
public void process(Exchange exchange) throws Exception {
Integer time = exchange.getIn().getBody(Integer.class);

logger.info("Processing data " + time);
Thread.sleep(time.longValue());
logger.info("Completed processing data " + time);
