custom exception framework. I have been working on this for the last few months and have now put together a running unit testing example to demonstrate the final results and committed this to the jBPM projects directory.
The idea is that you are now able to use a single exception handling process (see image provided) to provide all your processes with exception processing. There are only two options in this framework, a human task to allow fixing your processes problems by hand or a retry option to allow for automated continuation based on settings you define.
Currently the unit test demonstrates only human task fixing of a single node failure, but I will continue to work on this. I plan to complete a state node failure and demonstrate the Retry option.
The project includes maven dependency handling (see the pom.xml) and you can start in the readme.txt file included at the root level of the project.
