--- Comment #2 from echo <langren_q...@163.com> --- but, in my opinion. just the NioEndpoint$Poller.cancelledKey and NioEndpoint$Poller.run may cause the deadlock. Poller.run finally call AbstractSelector.cancel and Poller.cancelledKey finally call AbstractSelector.deregister. The two method all need the conditions keyLock and cancelledKeys. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
