java.awt.Robot works strangely under macOS Mojave

After macOS was upgraded to Mojave, java application that is using Java Robot and works absolutely fine under High Sierra, stars to work incorrectly. Symptoms are:

robot.keyPress(VK_N); causes about 7 the same errors and did not type anything.

2019-02-03 19:27:52.324 java[928:31672] pid(928)/euid(501) is calling TIS/TSM in non-main thread environment, ERROR : This is is NOT allowed. Please call TIS/TSM in the main thread!!!

robot.mouseMove works fine if I run it via Java command line, and doesn't work if I run the same class in Eclipse.

public static void main( String[] arg) throws AWTException, InterruptedException { Robot robot; robot = new Robot(); robot.waitForIdle(); robot.keyPress(VK_N); robot.keyRelease(VK_N); robot.waitForIdle(); robot.mouseMove(100, 100); Thread.sleep(500); robot.mouseMove(10, 10); }

According to the recommendation Robot.mouseMove does not work at all in Mac OS X I have added Java and Eclipse into Security & Privacy, click the Privacy tab toward the top, then choose Accessibility. It did not solve the problem. Moreover, I could not see any difference.

I went through this link https://eclecticlight.co/2018/09/17/managing-mojaves-privacy-protection-privacy-controls/ and ran "tccutil reset AppleEvents". But I did not get expected the dialog to add the pair of apps into Privacy=>Automation section of "System preferences"

my Java is 1.8.0_191, x86_64.

Any ideas on how to get that code to work in Mac OS Mojave?
