Update on lint warnings in the jdk repo

[Joe Darcy]

Hello,

I'm happy to report that after an extensive cleanup effort, raw types 
and unchecked warnings have been eliminated from the jdk repo and those 
warnings are successfully enabled in the build:

     8039102: Add raw and unchecked lint warnings to build of jdk repository
     http://hg.openjdk.java.net/jdk9/dev/jdk/rev/d766f563d30d

Next up, deprecation :-)
