Hello,
What is the purpose of setting some of them to 0 twice? (It's a new array which

Hi everybody,
There are already JMH crypto micros in the open corpus (a maven project):
http://hg.openjdk.java.net/code-tools/jmh-jdk-microbenchmarks/file/fc4783360f58/src/main/java/org/openjdk/bench/javax/crypto
that should be able to measure the benefit of this webrev against the
