Answer 1

In OpenJDK, the default Java stack size on Linux-amd64 is 1024 KB.
You may check this with the following command:

$ java -XX:+PrintFlagsFinal -version | grep ThreadStackSize
     intx CompilerThreadStackSize                  = 1024        {pd product} {default}
     intx ThreadStackSize                          = 1024        {pd product} {default}
     intx VMThreadStackSize                        = 1024        {pd product} {default}
