JDK-8154539 - Examine the desktop module's use of sun.misc.SoftCache
Description
When generifying SoftCache I discovered two potential type problems in it: I don't think it has worked properly ever. There appears to be only one place in the entire JDK where this class is used: sun.awt.SunToolKit. 

If this could be replaced by say just a WeakHashMap or equivalent with SoftReferences we could be able to get rid of more than 440 lines of SoftCache implementation in sun.misc, which currently is the root of most warnings in said package.
Comments
8154539 relocated SoftCache to the java.desktop module as sun.awt.SoftCache So sun.misc no longer has to worry about the 440 lines of code. So I think we can defer this to another release.

May be it is better to replace the SoftCache by sun.awt.image.ImageCache.

Added started generification effort. I've found two inconsistensies so far: ValueCell and V are used interchangibly as Object in one function. Entries, which seem to be meant to hold value calls get values (V) instead in the iterator
