RFR of lang level code migration patches

[Martin Buchholz]

(as always) Please don't modify jsr166 classes (ArrayDeque) here, since
they are maintained upstream in jsr166 CVS.  Since jsr166 targets a variety
of java runtimes in general, it tends to be a late adopter of new language
features.  Although it's probably time to start using jdk7 features.
