Hello, I've setup archiva as proxy to maven central. I'm using a recent snapshot build. I get sometimes (?) 500 errors when downloading artifacts. According to logs, this is a ConcurrentModificationException.
Is this a known bug ? Here is the stacktrace : 2007-04-02 10:11:25,392 [http-8888-1] ERROR [RepositoryServlet] - "Servlet.service()" pour la servlet RepositoryServlet a généré une exception java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(Unknown Source) at java.util.AbstractList$Itr.next(Unknown Source) at org.apache.maven.wagon.events.TransferEventSupport.fireTransferProgress( TransferEventSupport.java:117) at org.apache.maven.wagon.AbstractWagon.fireTransferProgress( AbstractWagon.java:350) at org.apache.maven.wagon.AbstractWagon.transfer(AbstractWagon.java:336) at org.apache.maven.wagon.AbstractWagon.getTransfer(AbstractWagon.java :199) at org.apache.maven.wagon.AbstractWagon.getTransfer(AbstractWagon.java :182) at org.apache.maven.wagon.StreamWagon.get(StreamWagon.java:80) at org.apache.maven.archiva.proxy.DefaultProxyRequestHandler.getFileFromRepository (DefaultProxyRequestHandler.java:541) at org.apache.maven.archiva.proxy.DefaultProxyRequestHandler.get( DefaultProxyRequestHandler.java:393) at org.apache.maven.archiva.proxy.DefaultProxyRequestHandler.getArtifactFromRepository (DefaultProxyRequestHandler.java:260) at org.apache.maven.archiva.proxy.DefaultProxyRequestHandler.get( DefaultProxyRequestHandler.java:196) at org.apache.maven.archiva.proxy.DefaultProxyRequestHandler.get( DefaultProxyRequestHandler.java:116) at org.apache.maven.archiva.web.repository.ProxiedDavServer.fetchContentFromProxies (ProxiedDavServer.java:156) at org.apache.maven.archiva.web.repository.ProxiedDavServer.process( ProxiedDavServer.java:144) at org.codehaus.plexus.webdav.servlet.multiplexed.MultiplexedWebDavServlet.service (MultiplexedWebDavServlet.java:111) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter( ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter( ApplicationFilterChain.java:173) at com.opensymphony.webwork.dispatcher.FilterDispatcher.doFilter( FilterDispatcher.java:189) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter( ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter( ApplicationFilterChain.java:173) at com.opensymphony.module.sitemesh.filter.PageFilter.doFilter( PageFilter.java:39) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter( ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter( ApplicationFilterChain.java:173) at com.opensymphony.webwork.dispatcher.ActionContextCleanUp.doFilter( ActionContextCleanUp.java:88) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter( ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter( ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke( StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke( StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke( StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke( ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke( StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service( CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11AprProcessor.process( Http11AprProcessor.java:833) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process( Http11AprProtocol.java:639) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java :1285) at java.lang.Thread.run(Unknown Source)
