It's javassist that hits VFSURLConnection a lot,
when trying to load annotations.
I'll see if I can re-write this to use VFS directly.

This would be the last on my list (priority wise)

I think jBPM BI should be a mixture:
- Some "probe" mechanism like Tom mentioned on transitions as somehow implemented by SeeWhy (but maybe less verbose for Ronald ;-))
- Some BestPratcises / Basic working examples for PEntaho integrations, especially a basic cube layout and an Kettle ETL process for the jBPM log data
- Some BPR reports for existing log data for generic performance indicators (process runtimes, task instance wait and run times, ...). This is what I think Heiko is working on at the moment, right?
- Some KPI descriptions like I mentioned earlier. Even if this may be a lot of domain data information, I think if the process processes this domain data anyway, it is not such a bad idea to calculate KPI's already out of that and send better business events to BAM (like SeeWhy does).

yes, you are right. the special variable was not a good idea. instead the same principle of associating generic KPI values should be added to the jBPM BI database.

the logs that are generated by default will already enable a log of PKI metrics without modelling them explicitely in the process. But for some, you need to generate extra data. Or e.g. extract the right information from the users domain model in order to get the KPI's into a generic scheme and display them without coding a custom query that spans over jBPM and user tables.
