Subject PROPOSAL : Apache Harmony - J2SE 5 Project
Date Fri, 06 May 2005 22:51:13 GMT
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 :

     harmony-dev@incubator.apache.org

You can subscribe by sending an email to

     harmony-dev-subscribe@incubator.apache.org

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 :

   Guy Churchward (individual w/ commercial VM experience)
   Joakim Dahlstedt (individual w/ commercial VM experience)
   Jeroen Frijters (IKVM)
   Geir Magnusson Jr. (Apache)
   Ricardo Morin (individual w/ commercial VM experience)
   Georges Saab (individual w/ commercial VM experience)
   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)
   Dalibor Topic (Kaffe)
   Tom Tromey (GCJ)
   Weldon Washburn (individual w/ commercial VM experience)

These individuals will participate as Incubator Mentors :

   Noel Bergman
   Ben Laurie
   Geir Magnusson Jr.
   Stefano Mazzocchi
   Sam Ruby
   Leo Simons
   Davanum Srinivas

The following Apache Members will be the sponsoring members :

   Noel Bergman
   Jason Hunter
   Ben Laurie
   Ted Leung
   Geir Magnusson Jr.
   Stefano Mazzocchi
   Sam Ruby
   Leo Simons
   Davanum Srinivas

The following community members support this effort :

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 :

     harmony-dev@incubator.apache.org

You can subscribe by sending an email to

     harmony-dev-subscribe@incubator.apache.org

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.
