<AWT Dev> RFR: 8155874: Fix java.desktop deprecation warnings about Class.newInstance

[Phil Race]

bug: https://bugs.openjdk.java.net/browse/JDK-8155874
Webrev: http://cr.openjdk.java.net/~prr/8155874/

This hits all across the desktop module, hence the cross-post.

The Class.newInstance() has been deprecated since it
may throw checked exceptions that are not declared.

Class.getConstructor().newInstance() was recommended as a
replacement but it will return only public constructors.

So if you have package access to a package private constructor it will 
fail where
as the previous pattern succeeded

So the recommendation now is to use 
Class.getDeclaredConstructor().newInstance()
and this fix uses that except for some cases where we have a limited and 
known
set of internal "service providers" which are known to use public 
classes and constructors.

Also some exception catching has been cleaned up as appropriate for the
new method call and taking advantage of the JDK 1.7 
ReflectiveOperationException
