[OpenJDK 2D-Dev] Review Request JDK-8129457: Disposer.pollRemove may fail to dispose

[prasanta sadhukhan]

Hi,

Please review a small fix for this issue where it seems if polling is 
performed before the bounds are checked then it may happen that "obj" 
maybe removed from queue without getting disposed if the bounds checks 
are exceeded. Fix is to check for bounds before polling the queue to 
remove the object so that we can bail out if bounds are exceeded before 
obj is removed from queue.
