[OpenJDK 2D-Dev] JDK9: RFR: 8039342: Fix raw and unchecked warnings in sun.awt.*

[Joe Darcy]

Hi Henry,

Thanks for looking into this. FWIW, while I was working on

         JDK-8039109: Fix unchecked and raw lint warnings in java.awt

I started looking at some sun.awt.* type too and I noticed the same 
problem in AreaOp.pruneEdges(). The comment I added to my in-progress 
webrev is:

  203         /*
  204          * The implementation of this method consistently treats its
  205          * return type either as a Vector<Edge> or a Vector<Curve>.
  206          */

so there does seem to be some internal inconsistency in what the Vector 
is meant to hold.

In any case, your changes look good to me. (I'll adapt my changes for 
8039109 based on your changes in this bug.)

Cheers,

-Joe
