Java adds concurrency annotations

[Paul D. Anderson]

The folks at Sun are adding standard annotations to Java 7 for security, concurrency, precondiitons and nullability, among others:

I wonder how these will play out in the real world. I'm especially interested in the @Immutable annotation since Java's pass-by-reference implementation makes immutability very difficult to implement.

Thanks again, Walter, for the transitive const paradigm. (Although I still contend that you got the keyword wrong: it should be "immutable" -- just like Java!!)
