The warning message is output by AtmosphereFramework.
Since HttpSessionListener provided by AtmosphereFramework is not used, this warning message is output.
Since a different implementation from HttpSessionListener will be used instead in intra-mart Accel Platform, there will be no effect on operation.
This warning message is output only at startup.
It is impossible to suppress the output of this warning message in the settings etc.
