Cometd Compatible with jetty 8.1.11

I am currently working on a project using cometd 1.0.0 and jetty 8.1.11.

I was getting the following exception: WARN:oejut.Timeout:EXCEPTION java.lang.NoSuchMethodError: org.eclipse.jetty.util.LazyList.removeFromArray([Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; at org.cometd.server.ClientImpl.removeSubscription(ClientImpl.java:495) at org.cometd.server.ChannelImpl.unsubscribe(ChannelImpl.java:339) at org.cometd.server.ClientImpl.unsubscribeAll(ClientImpl.java:527) at org.cometd.server.AbstractBayeux.removeClient(AbstractBayeux.java:526) at org.cometd.server.ClientImpl.remove(ClientImpl.java:370) at org.cometd.server.continuation.ContinuationClient.remove(ContinuationClient.java:220) at org.cometd.server.continuation.ContinuationClient$1.expired(ContinuationClient.java:60) at org.eclipse.jetty.util.thread.Timeout.tick(Timeout.java:140) at org.eclipse.jetty.util.thread.Timeout.tick(Timeout.java:153) at org.cometd.server.continuation.ContinuationBayeux$1.run(ContinuationBayeux.java:76) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462)

When i updated cometd to version 1.1.5, i cannot see this error anymore. but my cpu usage for jetty is quite high on load testing.

Can anyone suggest a stable version of cometd that is compatible with jetty 8.1.11.

CometD 1.x is not maintained anymore; CometD 2.x is out since July 2010.

I strongly recommend you to upgrade to CometD 2.x (current version 2.7.0), which will work fine with every Jetty 8 version, although I recommend you to use the latest Jetty 8, currently 8.1.14.v20131031.

Looking at the information on Maven Central, it appears that the first time Jetty8 is used by cometd itself first shows up in the metadata for Cometd 2.7.0.

However, it lists version 8.1.13.v20130916 as the one it uses itself, not version 8.1.11.

For completeness sake, here's the metadata for Cometd 2.6.0, notice it has no jetty8 reference.
