Hi Ruben,
Could you try again with 2.0 M7 and send us the stack trace that you get (if you get one)? It will be easier for us to fix any related bug.

Best regards, Thierry Boileau Hi, We tried with different versions of restlet (1.1-M1, 1.2-M1, 1.1.8) and we are having the same problem. we have a Resource. it make some access to a database. when it has severall calls at same time, one or more of them fails and throw an exception. We think it happens before entering into the Resource class, so we think it can be a bug. Here is the Stack trace GRAVE: Unhandled exception or error intercepted java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372) at java.util.AbstractList$Itr.next(AbstractList.java:343) at com.noelios.restlet.Engine.getPreferredVariant(Engine.java:704) at org.restlet.data.ClientInfo.getPreferredVariant(ClientInfo.java:463) at org.restlet.resource.Resource.getPreferredVariant(Resource.java:270) at org.restlet.resource.Resource.handleGet(Resource.java:439) at org.restlet.Finder.handle(Finder.java:353) at org.restlet.Filter.doHandle(Filter.java:150) at org.restlet.Filter.handle(Filter.java:195) at org.restlet.Router.handle(Router.java:504) at org.restlet.Filter.doHandle(Filter.java:150) at org.restlet.Filter.handle(Filter.java:195) at org.restlet.Router.handle(Router.java:504) at org.restlet.Filter.doHandle(Filter.java:150) at org.restlet.Filter.handle(Filter.java:195) at org.restlet.Router.handle(Router.java:504) at org.restlet.Filter.doHandle(Filter.java:150) at com.noelios.restlet.StatusFilter.doHandle(StatusFilter.java:130) at org.restlet.Filter.handle(Filter.java:195) at org.restlet.Filter.doHandle(Filter.java:150) at org.restlet.Filter.handle(Filter.java:195) at com.noelios.restlet.ChainHelper.handle(ChainHelper.java:124) at org.restlet.Component.handle(Component.java:673) at org.restlet.Server.handle(Server.java:331) at com.noelios.restlet.ServerHelper.handle(ServerHelper.java:68) at com.noelios.restlet.http.HttpServerHelper.handle(HttpServerHelper.java:147) at com.noelios.restlet.ext.servlet.ServerServlet.service(ServerServlet.java:881) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:214) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) at org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:198) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:152) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:137) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:118) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:102) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveContext.java:104) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:520) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:929) at org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:799) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:705) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:577) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:683) at java.lang.Thread.run(Thread.java:619) Regards R.Hernando ------------------------------------------------------ <http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2449449> http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2449449 ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2452567
