You can start working straight away!  but before we can accept your
contributions into the project we'll need to have a completed
questionnaire.  If you have not worked on a java implementation before
then it should only take a couple of minutes to complete.

See the contribution policy here:
    http://incubator.apache.org/harmony/contribution_policy.html

and the questionnaire here:
    http://incubator.apache.org/harmony/auth_cont_quest.html

You can use whichever compiler you want (ensuring it is 1.4 compliant
;-) ), and then can compare your results against any complaint java
implementation (e.g. Sun, BEA, IBM, ...).  Tests should be written to
the javadoc spec, rather than deducing behavior from any particular
implementation.

Thanks,
Tim
