Illegal reflective operation warning in Processing 4

[12people]

I get the following warning when using this library in Processing 4:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by gab.opencv.OpenCV (file:/Users/mirekmazel/Documents/Processing/libraries/opencv_processing/library/opencv_processing.jar) to field java.lang.ClassLoader.sys_paths
WARNING: Please consider reporting this to the maintainers of gab.opencv.OpenCV
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

Currently I see at least one version updated for Processing 4; maybe @jaegonlee can send a PR.
