OpenJDK 64-Bit Server VM warning - EC2 war file about opencv HOT 6 CLOSED

This warning can be pretty much ignored. See https://groups.google.com/forum/#!topic/fusionreactor/iRsnTT3al04. If it concerns you, I would welcome a pull request to fix the build process.

I got the following warning:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by nu.pattern.OpenCV$SharedLoader (file:/home/martin/.m2/repository/org/openpnp/opencv/3.2.0-0/opencv-3.2.0-0.jar) to field java.lang.ClassLoader.usr_paths
WARNING: Please consider reporting this to the maintainers of nu.pattern.OpenCV$SharedLoader
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /tmp/opencv_openpnp6598848942071423284/nu/pattern/opencv/linux/x86_64/libopencv_java320.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 ', or link it with '-z noexecstack'.

I'm pretty sure this will become more than a warning in Java 17 which is right around the corner and LTS

Right...

@vonnieda could you give a little more details of what should be fixed in the build process?
