Huh? Java "protected from decay and dilution"?
Witch the exception of SUN never liking native interface linking, Java was ANYTHING BUT protected from decay. Java went about adding and adopting stuff, from Swing to generics to annotations to functional stuff, to remoting, to various EE fads of the day, without ever thinking about whats best about the core language and how to keep it clean and agile.
I would have liked it if in place of Java we had a purer language, like, say, Smalltalk.
