The robot does not properly set/use key modifiers after JDK-8155740.

The issue became critical when one test presses/unpresses the META/SHIFT/etc keys, but the robot generate only the press event, this cause all possible weird results for the later tests.

For example every tests runs on macOS open lots of utility windows of terminal becaouse one test press Command key, and one another test try to press different keys which apparently became shortcuts(CMD+XXX), example one of the shortcut is CMD+H to hide the current test window(terminal became the focus window), and second is CMD+I to open utility window of the terminal.
