In the realese page I get the next info

WSO2 API-M 2.6.0 is based on WSO2 Carbon 4.4.35 and is expected to be compatible with any of the WSO2 products that are based on any Carbon 4.4.x version...

And if you see the valve folder for 4.4.35 version, there is not a java class for RequestCorrelationIdValve. So How I can fix this error? I see that the WSO Carbon 4.6 server have the java class RequestCorrelationIdValve
