Re: [jetty-users] Meaning of "java.lang.IllegalStateException: s=ASYNCIO i=false a=COMPLETE" error message?
Refers to the state tracking in HttpChannelState .

See https://github.com/eclipse/jetty.project/blob/master/jetty-server/src/main/java/org/eclipse/jetty/server/HttpChannelState.java#L161-L167

s = state
i = initial
a = async

I found the root cause of the issue- a buggy section of the code was completing the async context and when other sections of the code were trying to access the context (which is now complete), "java.lang.IllegalStateException: s=ASYNCIO i=false a=COMPLETE" is thrown. Makes sense. I am still curious to know what does "s", "i" and "a" stand for? 

I am using Jetty v9.1.0.v20131115. Complete stacktrace:

With Jetty 9.1.0 its likely from HttpChannelState.getStatusString(), but without more context of your stacktrace, it would be hard to explain what is going on.

Also, we need *MUCH* more context for that particular exception.
Such as more lines of the stacktrace.  As an IllegalStateException depends heavily on what was going on.

I am getting this error message intermittently.

Thanks,
