Hi Menaka,
According to the debug info that you attached, AFAIU this caused
because inputStreamHandler
is null and inputStreamHandler.getOutput() throws NPE.
I think you can use ServerConfigurationManager instead of CarbonServerManager
to do the restart.
e.g.
ServerConfigurationManager serverConfigManager = new
ServerConfigurationManager(automationContext);
serverConfigManager.restartForcefully();
Thanks
