10.12 introduced touch types
typedef NS_ENUM(NSInteger, NSTouchType) {
    NSTouchTypeDirect,      // A direct touch from a finger (on a screen)
    NSTouchTypeIndirect,      // An indirect touch (not a screen)
} NS_ENUM_AVAILABLE_MAC(10_12_2);

Our code uses normalizedPosition selector which produce crash for NSTouchTypeDirect events JDK-8172847 . 

We should check that touch events works correctly on touch screens.
