Announcing Jikes RVM 3.0 + Apache Harmony!
Announcing Jikes RVM 3.0 + Apache Harmony! We are pleased to announce the
release of Jikes RVM 3.0, an open-source meta-circular JVM written in Java.
A new feature of the release is initial support for Apache Harmony's class
library.
What is Jikes RVM? Jikes RVM is a research virtual machine capable of
running the latest Java programs. Writing a JVM in Java has many advantages
including access to libraries such as* java.util.concurrent*, the use of
IDEs like Eclipse and the use of annotations to extend the language and
virtual machine. Jikes RVM is now over 10 years old and has been used in
more than 190 refereed research papers.
Support for Apache Harmony Jikes RVM is built using Apache Ant, getting the
build to compile and use Apache Harmony's class library is as simple as
defining the *classlib.provider* property to be *Harmony*. For example, to
download and build Jikes RVM with Apache Harmony:
1. download the Jikes RVM from
http://sourceforge.net/project/showfiles.php?group_id=128805
2. extract the files
3. build Jikes RVM using Apache Ant and specifying what kind of Jikes RVM
configuration you would like and what kind of host you have. The prototype
configuration is recommended at the moment. To test the performance of the
optimizing compiler use a production build but this may have problems - see
features of the build below. To build on x86_64 linux, for example, run:
*ant -Dconfig.name=prototype -Dhost.name=x86_64-linux
-Dclasslib.provider=Harmony*
4. following the build the executable will be placed in the
*dist*directory, for example the previous build will put the RVM in
*dist/protoype_x86_64-linux*.
The build process will take Apache Harmony's class library from SVN, build
it and then build the Jikes RVM using it. Once built the Harmony libraries
won't be rebuilt and a typical prototype build will complete in under 2
minutes.
We need you help!
We hope you will try out Jikes RVM 3.0 with Apache Harmony. There are many
known and unknown problems and potential improvements, please help us to
find what these are, which of these are priorities and also please feel free
to send us your patches! The Jikes RVM is licensed under the CPL (the
predecessor of the EPL). Apache Harmony can also help us, for example, by
providing a separately packaged version of the class library so that we
don't need to take it from SVN.
The following URLs explain more:
1. the Jikes RVM web site: http://jikesrvm.org/ (you can find in here how
to develop Jikes RVM using IDEs like Eclipse)
2. the Jikes RVM JIRA bug and feature tracking system:
http://jira.codehaus.org/browse/RVM (a category of which is bugs and
features relating to Apache Harmony class library support)
<http://goog_1218120927426/>
<http://goog_1218120927426/>Some features of the build The Jikes RVM
provides an optimizing compiler, an adaptive optimization system and
on-stack replacement. When being built on a bootstrap JVM it can use the
optimizing compiler, a feature of which is to follow references of final
fields. There is the possibility of confusion as the boot strap JVM's class
library and Apache Harmony's class library may not match, there are various
fixes to deal with this, but an alternative is to use the baseline compiler
(as in the prototype build).
The Jikes RVM version of the Harmony kernel classes are provided in the *
libraryInterface* directory. Code in this directory may be licensed under
different licenses than the CPL.
Jikes RVM comes with the MMTk garbage collectors and the VM magic classes
may already be familiar to Apache Harmony developers.
Testing your build The Jikes RVM performs Continuous Autonomous Testing, the
results of which are tracked here: http://jikesrvm.anu.edu.au/cattrack/
The scripts that test Jikes RVM are part of the distribution. For example,
to build and test Jikes RVM 3.0 with SPEC JVM 2008 run:
ant -f test.xml -Dconfig.name=prototype -Dhost.name=x86_64-linux
-Dclasslib.provider=Harmony -Dtest-run.name=SPECjvm2008
This will automatically download and install the benchmark in the Jikes RVM
distribution before building and testing Jikes RVM 3.0 with it.
Acknowledgments
In getting Jikes RVM and Apache Harmony working together we were lucky to
receive support and help from Tim Ellison and Mark Hindess.
Thanks Thank you for your interest in this milestone in Jikes RVM's
development and we look forward to your help in finding bugs and improving
Jikes RVM!

It would be much, much better if we fixed things to use the zip cache
pool api - classlib built with -Dhy.zip.api=true - rather than fixing
it to use the current obsolete/unclean API.

Hi,
In order to make the integration easier, can we pull in the minor
patch [1] into the Harmony trunk? That would enable JikesRVM to use
prebuilt Harmony snapshots.

I have not finished this announcement but can't help to try.
It sounds great. Thank you all.
ASFAIK, contribute APL-licensed code to JikesRVM is all right,
but i think there are some concerns when fetching code from JikesRVM.
Correct me if i was wrong!
Maybe we can create a page for the JikesRVM building and testing later.

I had filed RVM-615 [2] with little fix that enables copying of

I'm afraid I haven't written the build to do this but it would be a
great extension, please open JIRA issues. There may also be some issues
as we use some CFLAGS when building Harmony.

I hope this is ok, but it's worth discussing this on our mailing lists
too. Possibly Michael Hind knows.

Thanks a lot, Ian!
What a coincidence, I started building Jikes RVM three hours ago, when
the latest version was 2.9.3 :) I had googled around and see "Apache
Harmony classlib support" in JIRAs, but stuck with build system that
can't understand what do I want from it.
Time to get Jikes RVM 3.0! I would report back on my progress.
A couple of starter questions though:
1. Can I point Jikes RVM build system the location of my own Harmony
classlib trunk?
2. (legal, more to Tim) Are CPL and APL compatible? Can I study
CPL-licensed code and contribute back to Harmony DRLVM? Can I
contribute APL-licensed code to JikesRVM?
Thanks,
Aleksey.
