Contrary to logback-classic, there is no AsyncAppender class in logback-access. Please file a jira issue requesting this feature for logback-access. On 01.05.2013 19:40, Roberto Ferreras wrote:
After setting up AsyncAppenders for the application log, I tried to use them on the request log (I am using Jetty) and I get this exception:

Later I have found at the docs "AsyncAppender logs ILoggingEvents asynchronously", so it seems that they can't be used with logback access, is that correct?
Thanks.
