Re: [jboss-dev] [infinispan-dev] concurrency issue on ServiceLoader::iterator

Anyone ever seen this error? Caused by: java.util.NoSuchElementException at java.util.AbstractList$Itr.next(AbstractList.java:350) [classes.jar:1.6.0_31] at java.util.Collections$1.nextElement(Collections.java:3389) [classes.jar:1.6.0_31] at java.util.ServiceLoader$LazyIterator.hasNext(ServiceLoader.java:332) [classes.jar:1.6.0_31] at java.util.ServiceLoader$1.hasNext(ServiceLoader.java:415) [classes.jar:1.6.0_31] at org.infinispan.distexec.spi.DistributedTaskLifecycleService.onPreExecute(DistributedTaskLifecycleService.java:50) [infinispan-core-5.2.0-SNAPSHOT.jar:5.2.0-SNAPSHOT] public <T> void onPreExecute(Callable<T> task) { try { Iterator<DistributedTaskLifecycle> i = loader.iterator(); while (i.hasNext()) { // <------------------------------------------------- we CHECK before DistributedTaskLifecycle cl = i.next(); cl.onPreExecute(task); And I doubt I have multiple thread accessing it at the same time -- running this from serial testsuite. I can reproduce this, atm, almost every time, where Vladimir (Blagojevic; Infinispan - author of DistributedTaskLifecycleService) cannot. Any idea? -Ales _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
