JDK-8088535 Memory Leak

[John Hendrikx]

I tested this, and it seems to still not work quite right.

As far as I can see, it is not a memory leak, just slow performance when 
subtracting many shapes from roughly the same location from another 
shape.  When the shapes are more spread out, it performs better.

I don't think it is a major issue, definitely not for regular uses of 
shapes.

Doing "game" like graphics is often an exercise to find how an API can 
be best exploited to get what you want with good performance; telling an 
API to brute-force render 10000 points in a 100x100 grid for example 
won't perform well, put them on a texture instead and it will perform well.

This seems to be a similar case, so I'd recommend to use a Canvas, and 
draw circles on that instead.
