Lock screen doesn't locks Java application interaction

Actions

1. Open java applicaiton (i've used Intellij Idea).

2. Lock Mac OS screen.

3. Move mouse to place of some controls with popup menu.

4. Click on menu item.

Result

Popup menu shown on locked screen, click action performed without need to unlock screen.

Expected result

Popup menu must not be shown, mouse cursor must not be changed when moving over invisible Java controls, action must not be performed.
