ARM API Support

[Paul Benedict]

David,

I like this project!

I wonder if the effort to retrofit classes with ARM is being too
conservative. AutoCloseable is a new feature and no current code uses it.
It's impossible that its introduction on existing classes would have
unintended side-effects because the semantics are not automatic -- the
interface is benign until the ARM syntax is used in source and recompiled.

Kudos to David for this. Even if JDK 7 won't retrofit every case, libraries
like this can help close the gap.
