Server log with UNEXPECTED ERROR

Description of problem:
Please inspect the server.log attached, in particular the UNEXPECTED ERROR at 03:58:28. This occurred in the automated GUI test run of business cetral. The only thing the test was doing was navigating to Dashboard > Business Dashboard in business central and checking the presence of one KPI (not interacting the page in any way). The test passed (The KPI was there) but the ConcurrentModificationException appeared in the server log by the time the jBPM Dashboard was opened.

Version-Release number of selected component (if applicable):
BPMS 6.0.0 CR1 on RHEL 6 with PostgreSQL 9.2 as datasource

How reproducible:
It will be hard to reproduce.

Steps to Reproduce:
1. In business central navigate to Dashboard > Business Dashboard

Actual results:
Exception in server log

Expected results:
no exception
