> ServerName calss，the getServerName(String hostName, int port, long startcode),equals and compareTo are case insensitive, but getHostname() is case sensitive.
> if hostName is HOSTNAME1, ServerName is hostname1,11111,1589615319931, and getHostname() returns HOSTNAME1.
> and then BaseLoadBalancer#retainAssignment() uses ServerName#getHostname(), all keys of serversByHostname are upperCase(HOSTNAME1,HOSTNAME2,HOSTNAME3,HOSTNAME4...) from ServerManager#createDestinationServersList, but oldServerName.getHostname() is lowerCase(hostname1,hostname2,hostname3...) from walLog dir.

> and finally...all region of old ServerName will be assigned to random hosts
