Using the 1.1.3 or 1.1.4 API jar, I intermittently get exceptions like this:

Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: OpenCV(3.4.2) C:\build\3_4_winpack-bindings-win64-vc14-static\opencv\modules\core\src\matrix.cpp:367: error: (-215:Assertion failed) u != 0 in function 'cv::Mat::create'

        at com.illumon.guitest.TestIrisGui.main(TestIrisGui.java:372)

Line 179 of TestIrisGui is in the midst of a try/catch(Exception) block, but it does not catch this exception, and, in fact, the whole process tree may get killed when this occurs. 

Any ideas?

Thanks,
Paul
