Issue while logging MDC values with Jetty 12

[narharim]

We have a service A that initiates an API call to another service B. In response service B transfers zip file in chunk to service A. We have written a custom response listener which transfer chunk from service A to its client without storing it in buffer.

while doing so when ever connection is aborted from client of service A, key-value pair which we are inserting into MDC map are getting cleared out and we are unable to log those key-value.

for example
MDC.put(ABORTED, "true") is not printed in log
