RFR [9] 8039470:URLConnection.getContent incorrectly specifies the default location of content handler classes

[Chris Hegarty]

java.net.URLConnection.getContent() incorrectly specifies the default location of content handler classes as sun.net.www.content. ( this location is implementation specific ) 

  "If no content handler factory has yet been set up, or if the factory's createContentHandler method 
    returns null, then the application loads the class named: 
         sun.net.www.content.<contentType> " 

This should be changed to something like: 
    <system default package>.<contentType>, similar to what is done in URL [1]
