JDK-7027157 - Project Coin: javac warnings for AutoCloseable.close throwing InterruptedException
Description
As part of warnings cleanup day, it was noted that javac -Xlint:all will warn about the declaration of java.lang.AutoCloseable.close being about to throw InterruptedException.

Since this is a required part of the platform, it is neither helpful not necessary for javac to warn about this particular close method.
