RFR: JDK-8212780: JEP 343: Packaging Tool Implementation

[Phil Race]

Question .. why is "mac", "linux" and "windows" necessary in the package 
name here ?

  src/jdk.jpackager/macosx/classes/jdk/jpackager/internal/mac/MacAppBundler.java
  src/jdk.jpackager/windows/classes/jdk/jpackager/internal/builders/windows/WindowsAppImageBuilder.java
src/jdk.jpackager/linux/classes/jdk/jpackager/internal/linux/LinuxRpmBundler.java

There's not likely to be a clash, so is there some other reason not to 
want these
in the same package as the shared internals like
src/jdk.jpackager/share/classes/jdk/jpackager/internal/Param.java

?
