Java HotSpot(TM) Server VM warning: You have loaded library /tmp/libnetty-transport-native-epoll7650900490225298142.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

This warning pops up on startup of the server.
'execstack' is not a terminal / java command
