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

[Henry Jen]

Hi,

Please review the webrev cleans up raw and unchecked warnings in sun.awt,
http://cr.openjdk.java.net/~henryjen/jdk9/8039342/0/webrev/

The following changes in AreaOp::pruneEdges() is particular worth 
attention, when numedges < 2, two different type are mixed up in the 
past with use of rawtypes; However, I think it could only work if the 
Vector is empty?

Cheers,
Henry
