i just checked in some good progress in getting to a clean API for the pvm. also the javadocs for the pvm should be in a fairly decent state.
i'm trying to finalize the pvm api and i could use your help to do a proper evaluation at this point.
i have cleaned up the API in org.jbpm.pvm as much as i could. i think it is already pretty stable now.
but to really finalize it, i still need to do 2 things : build jpdl and review the persistence mappings.
