switch / feature UseStringCache & status

[Krystal Mo]

Hi Chuck,

I don't think this feature ever made it to JDK7. Both 
UseCompressedString and UseStringCache were Oracle/Sun JDK6-only 
features, which weren't present in either OpenJDK 6/7/8 nor JDK7/8 and 
on. So it's not "removed" in JDK7, it just never existed.

Hope that helps,
Kris
