As Java HA windows failover test

hi everyone,

i have one small question while i'm testing a HA failover test scenario.

I have installed a NW7.5 java stack on Windows, and configured two nodes for HA, each node has a java instance. when i kill the msg_server.exe process, i think the message server should be automatically restart and it did restart, but after restart two java instance came into yellow state, and after 3 minutes it came backup green.

but when we switch over the SCS from one node to another node manually, those java instance are green all the time.

so may i ask is it normal after we kill msg_server process, java instance will restart ?

there are some logs found in work directory:
