Dear Incubator PMC :
We, the sponsoring members listed below, ask that you accept the
following proposal for a new project at Apache, an effort centered
around architecting and implementing J2SE 5.
Note to all :
We have established a list for discussions to keep project-specific
mail traffic from overwhelming the general incubator list. Unless
your comment is directed to the general Incubator community or the
Incubator PMC, please post everything Harmony-related to :
[EMAIL PROTECTED]
You can subscribe by sending an email to

Until this proposal has been accepted by the Apache Incubator PMC,
these lists are provisional and do not constitute official lists
for the project.
Project Harmony
===============
Motivation
----------
There is a clear need for an open-source version of Java 2,
Standard Edition (J2SE) runtime platform, and there are many
ongoing efforts to produce solutions (Kaffe, Classpath, etc).
There are also efforts that provide alternative approaches to
execution of Java bytecode (GCJ and IKVM). All of these efforts
provide a diversity of solutions, which is healthy, but barriers
exist which prevent these efforts from reaching a greater potential.
Proposal
--------
We propose that we create a new Apache project, Harmony, that will
achieve the following goals :
1) create a Compatible, independent implementation of J2SE 5
under the Apache License v2
2) create a community-developed modular runtime (VM and class library)
architecture to allow independent implementations to share runtime
components, and allow independent innovation in runtime components
In doing so, we intend to create a broad, collaborative community
of contributors, implementors and users of the modular platform
specification.
To begin, we propose the following as a basic architectural
blueprint as a starting point for our discussion :
http://people.apache.org/~geirm/harmony.jpg
We will create directly, via inclusion of independent third-party
code, or through contribution :
a) a freely implementable specification of a modular VM
and class library that allows for multiple, independent
implementations
b) a test suite for interoperability testing of the modules
c) an implementation under the Apache License of the modular VM
d) a class library under the Apache License compatible with
the J2SE 5 specification that implements the defined interfaces
We will start with this mechanism because we desire to :
- have a simple plan upon which coding can immediately begin
- ensure that we have a focal point to begin the conversation
among interested members of the community
- have a clearly defined set of technical needs to allow
potential contributors, either code contributors or
individual participants, a basis for consideration
- ensure that this is a community effort - together we will
architect and implement via fresh new code or donation
- produce a set of specifications/designs allowing multiple
interoperable implementations that allow for sharing,
extension and innovation
We propose that the following people are considered the starting
participants. This set represents members from across the
community, this diversity a factor we wish to start with and
preserve as we grow.
These individuals have expressed an interest in participating in
the architecture and design work. The information in parenthesis
indicates other community participation or relevant experiences of
that individual :

Joakim Dahlstedt (individual w/ commercial VM experience)
Jeroen Frijters (IKVM)
Geir Magnusson Jr. (Apache)

Bruno Souza (SOUJava)
Davanum Srinivas (Apache)
Dalibor Topic (Kaffe)
Tom Tromey (GCJ)
Weldon Washburn (individual w/ commercial VM experience)
Mark Wielaard (Classpath)
and the following individuals have expressed interest in
participating as committers for the Apache-licensed implementation :
Jeroen Frijters (IKVM)
Ben Laurie (Apache)
Geir Magnusson Jr. (Apache)
Ricardo Morin (individual w/ commercial VM experience)
Bruno Souza (SOUJava)
Davanum Srinivas (Apache)

Tom Tromey (GCJ)
Weldon Washburn (individual w/ commercial VM experience)
These individuals will participate as Incubator Mentors :

Sam Ruby
Leo Simons
Davanum Srinivas
The following Apache Members will be the sponsoring members :

Operating Considerations
------------------------
0) We have established a list for discussions. Unless your comment
is directed to the general Incubator community or the Incubator
PMC, please post everything to :

Until this proposal has been accepted by the Apache Incubator PMC,
these lists are provisional.
1) Due to the various known and unknown risk factors of this
project, we propose that in addition to the required Individual
Contributor License Agreement (ICLA) we shall require that any
committer to Harmony will have a Corporate Contributor License
Agreement (CCLA), when appropriate, on file with the ASF Secretary,
and will keep that document current with respect to current
employer to preserve committer status. We do this in order to help
protect the community, both contributors and users, from
unauthorized incorporation of code or other intellectual property.
2) Historically, there has been wide exposure to VM and class-
library-specific source code that is the property of Sun
Microsystems as well as others, as it is common for commercial J2SE
implementations to be based on licensed Sun code. We wish to make
every effort to ensure that the licenses and rights of external
projects and efforts is properly respected. To that end, we will
explore additional ways to work with the Apache Incubator to ensure
that all IP is carefully monitored and tracked as it enters the
project.
