Hi Prasanta,
Please review the updated webrev,
http://cr.openjdk.java.net/~arapte/8039081/webrev.04/
Updated with call to tooltip.dispose(), as you suggested to dispose it before even GC.
Regards,
Ambarish

But we call
tooltip = new InfoWindow.Tooltip(eframe, target, this); just like balloon = new InfoWindow.Balloon(eframe, target, this); so should it not get disposed like balloon?
