When I run monitor program, I had this error:

insandjaja@pop-os:~/intelFPGA_lite/18.1/University_Program/Monitor_Program/bin$ ./intel-fpga-monitor-program

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/insandjaja/flexdock/RubberBand.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'.
