JDK 9 RFR of JDK-8098582: Remove redundant package.html file in javax.xml.ws/wsaddressing

[joe darcy]

Hello,

Not sure the best place to send this out for review / send it upstream, 
in any case, pressing forward please review this change to fix

     JDK-8098582: Remove redundant package.html file in 
javax.xml.ws.wsaddressing
     http://cr.openjdk.java.net/~darcy/8098582.0/

The package javax.xml.ws.wsaddressing has both a package-info.java file 
and a package.html file. While belts and suspenders are sometimes 
helpful, this is not one of those times. Having both files causing a 
javadoc warning; the fix is to copy the documentation from package.html 
into package-info.java and delete package.html.

Thanks,

-Joe
