I found “Default Mailbox” definition in Akka 2.2 – AkkaJava.pdf
However , in the lastest 2.6.20 version , I did not find any support .I think the function was deleted or a new implementation was replaced ,but I did not find it .
My purpose is that in a cluster environment, when a server goes down ,ensure that the mailbox messages in this server will not be lost and will continue to be executed on another server in cluser.
How can I do it ?（I use java）
Thanks for your help.
