Re: Async logger not logging after upgrading tomcat, jdk and log4j

of Log4j is concerned, our upcoming 3.0.0-beta2 will feature a separate `log4j-async-logger` artifact with a non-optional dependency on `com.lmax.disruptor:disruptor`[3]. We hope to relieve users from the burden of upgrading the Disruptor library themselves and rely on the transitive dependency in `

The busy-spin wait strategy is not something I want to promote since it basically dedicates a full core to the logging background thread. It's there mostly for testing and perhaps for hardcore users who are familiar with the Disruptor. Sent from my iPhone > On 2016/06/14, at 3:24, Matt Sicker
