What is new and interesting in JDK 7?

I wanted to document the most interesting features of JDK 7 here, for my own gratification and to make a place where you can contribute your great finds:

Invokedynamic bytecode for doing runtime binding of callsites
Named regular expression groups
Try with resources / AutoCloseable
MethodHandles
BufferPoolMXBean — where did all my memory go?
SocketOption, ProtocolFamily and NetworkInterface
Async IO — including filesystem notifications and a new network stack
ForkJoinPool
TransferQueue
Precise exception rethrowing, catching more than one exception type
Switch on String
Much better GZIP support
Global logger and other log management stuff
ThreadLocalRandom
Bitset.valueOf() for arrays
Paths for manipulating file paths
Files for copying files and streams, etc. Swiss army knife of stuff
File attributes, ACLs, etc.
Long.compare — probably caused a lot of bugs
Tons of Locale / Character updates

Things I found that are old but new to me:

Scanner — using all regexes, probably horribly inefficient
PriorityQueue, Deque
Atomic*FieldUpdaters

Am I missing anything?
