Hi Jan, Thanks for the report. Could you enter an issue in our tracker to keep track on this? Precise instructions to run the client-side tools/lib causing the problem would help a lot. http://www.restlet.org/community/issues
Regarding the BrokenCyclicBarrier causing a potential infinite loop, I just fixed the issue in SVN trunk. However, the is probably something else wrong to put the internal HTTP server in such as state. This needs to be reproduced on our side in order to be fixed.

I am now using http client in python, which solved the problem there. when I do: urllib.request.urlopen('http://localhost:8182').read() i get the following issue/exception thrown: Unable to block the thread at the cyclic barrier java.util.concurrent.TimeoutException at java.util.concurrent.CyclicBarrier.dowait(CyclicBarrier.java:222) at java.util.concurrent.CyclicBarrier.await(CyclicBarrier.java:399) at org.restlet.util.SelectionRegistration.block(SelectionRegistration.java:173) at org.restlet.engine.io.NbChannelInputStream.onFill(NbChannelInputStream.java: 226) at org.restlet.engine.io.Buffer.process(Buffer.java:594) at org.restlet.engine.io.NbChannelInputStream.read(NbChannelInputStream.java:30 9) at java.io.InputStream.read(InputStream.java:85) at org.restlet.engine.io.BioUtils.exhaust(BioUtils.java:235) at org.restlet.representation.Representation.exhaust(Representation.java:244) at org.restlet.engine.connector.ServerOutboundWay.onCompleted(ServerOutboundWay .java:172) at org.restlet.engine.connector.HttpServerOutboundWay.onCompleted(HttpServerOut boundWay.java:114) at org.restlet.engine.connector.OutboundWay.processIoBuffer(OutboundWay.java:40 7) at org.restlet.engine.connector.Way.onSelected(Way.java:409) at org.restlet.util.SelectionRegistration.onSelected(SelectionRegistration.java :284) at org.restlet.engine.connector.Connection.onSelected(Connection.java:579) at org.restlet.util.SelectionRegistration.onSelected(SelectionRegistration.java :284) at org.restlet.engine.connector.ConnectionController.onSelected(ConnectionContr oller.java:187) at org.restlet.engine.connector.ServerConnectionController.onSelected(ServerCon nectionController.java:97) at org.restlet.engine.connector.ConnectionController.selectKeys(ConnectionContr oller.java:260) at org.restlet.engine.connector.ConnectionController.doRun(ConnectionController .java:145) at org.restlet.engine.connector.Controller.run(Controller.java:155) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.ja va:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:9 08) at java.lang.Thread.run(Thread.java:662) My Code to start the server: try { new Server(Protocol.HTTP, 8182, JobStatusResource.class).start(); } catch (Exception ex) { Logger.getLogger(PGMonitor.class.getName()).log(Level.SEVERE, null, ex); } My Server Resource class: In my test case no jobs are running, otherwise I have one scheduledthreadpool executor per server i connect to with ~4 tasks waiting at different intervals. public class JobStatusResource extends ServerResource { @Get public String overview() { System.out.println("got request"); String result = ""; for( AGatherer g : PGMonitor.getJobList() ) { if(!result.equals("")) result += ","; result += "{ \"name\": \"" + g.getName() + "\", \"lastRun\": " + g.getLastRunFinishedInSeconds() + ", \"runtime\" :" + (g.getLastRunFinishedInSeconds()-g.getLastRunInSeconds())+ "} " ; } System.out.println("finished building content"); return "{ \"current_time\" : " + System.currentTimeMillis()/1000 +" , \"jobs\": [" + result + "] }"; } } any feedback on what I am doing wrong or should change is appreciaded. thanks for your efforts, Jan ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=28486 90 ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2849864
