The deprecated Socket constructors can be used to create a Socket that 
uses UDP. This means the new SocketImpl has to support the creation of 
UDP sockets and use the ResourceManager to enforce limits when running 
with a  security manager.  So it's just increasing test coverage as I 
wasn't able to find any tests in test/jdk that exercise it.
