i was working on a few things at a time. so i lost track and couldn't commit properly change by change. did bulk commit instead :-(
* throwing of NullPointerExceptions was replaced with JbpmExceptions
* some updates and tests surrounding the new job executor. there is still an open issue present on which i am still working.
* i added the jpdl/dist subproject, which builds the distribution packages. 1 zip for the runtime and one for the suite. check it out. i'm proud of it :-)
