Publicly or privately the answer is still no. zAAP processors run JAVA
code in the IBM-supplied JVM. Period. IBM has disclosed statements of
direction concerning certain functions that may become eligible to run
on the offload engines in a future release but as far as I know zAAPs
will still be JAVA only. 

As Ed mentioned somewhere earlier, the interface to the zAAP has not
been disclosed - although a few people outside IBM have a pretty good
idea how it works. For all practical purposes it is a private interface
between the JVM and the dispatcher and even though we know how it works,
it would be a direct violation of the T&Cs to even try to circumvent it.
In contrast, the interface to the zIIP -is- disclosed to vendors under
license. Meaning "we know but we can't tell you". Both are intentionally
limited in the work they can run.

Don't bother reading between the lines. It's touted as a JAVA processor
because it is a JAVA processor. It is just an ordinary z cpu engine, but
the OS makes sure that only JVM work runs on it. Ergo "it's a JAVA
processor".

The zAAP -name- came very late in the game. When it was first disclosed
to us it was called an IFA, which probably stood for "integrated
facility for applications" as you suggest. However, after the marketers
had their way with it, the name became zAAP. That happens a lot. The
lesson is not to read any intelligent meaning into the names. Often
enough the names are just the product of a fevered marketing brain.
