[9-dev] RFR: JDK-8142439: Ensemble8 media player slider issues

[Morris Meyer]

Kevin and Vadim,

Could you please review my changes for the post-commit cleanup to 
JDK-8144354?

Vadim regarding folding:

                 if (timeSlider.isValueChanging()) {
                     // multiply duration by percentage calculated by 
slider position
                     if (duration != null) {
mp.seek(duration.multiply(timeSlider.getValue() / 100.0));
                     }
                     updateValues();

                } else if (Math.abs(now.doubleValue() - 
old.doubleValue()) > 1.5) {
                    // multiply duration by percentage calculated by 
slider position
                    if (duration != null) {
mp.seek(duration.multiply(timeSlider.getValue() / 100.0));
                    }
                }

Pretty sure that is correct and cannot be folded as the updateValues() 
is necessary when with a slider changed value, and the click to seek 
value needs to stay unchanged.

Thanks much,
