Leyden EA 2 Build is available

[ioi.lam at oracle.com]

We are happy to announce the availability of the Leyden EA 2 Build:

      https://jdk.java.net/leyden/

Since the Leyden project started, we have successfully delivered several
Ahead Of Time (AOT) optimizations in the mainline JDK:

     JEP 483 - Ahead-of-Time Class Loading & Linking
     JEP 514 - Ahead-of-Time Command-Line Ergonomics
     JEP 515 - Ahead-of-Time Method Profiling

This EA allows users to try out new experimental AOT
optimizations that are not yet integrated into the JDK mainline:

     AOT compilation of Java methods
     AOT generation of Dynamic Proxies and reflection data
     AOT optimization for class lookup
     Early termination of AOT training run

Leyden is super easy to use and just works. To instantly try out Leyden
on your apps, you can first perform a training run with a single flag

     $ java -XX:AOTCacheOutput=app.aot -cp app.jar App

Rerunning your app a second time with the  -XX:AOTCache flag will show 
benefits
from the AOT cache:

     $ java -XX:AOTCache=app.aot -cp app.jar App

Details of the Leyden EA 2 Build, as well as HOWTO instructions can be
found at the release notes:

Please give it a try. We would love to hear your experiences, positive
or negative, so that we know how to improve the optimizations before
they are integrated into future Java releases. Please join the Leyden 
mailing
list at https://mail.openjdk.org/mailman/listinfo/leyden-dev and send your
feedback via e-mail to leyden-dev at openjdk.org.

This work would not have been possible without the participation of the
Java community. We would like to thank everyone who has contributed to
the Leyden project, especially our partners at Amazon, Google, Microsoft,
Red Hat and Spring for their ideas, time and energy to make this
project a success.
