Issue Summary

DVCS accounts are synchronized using only one thread. The setting dvcs.connector.synchronization.threads_per_consumer has no effect.

Steps to Reproduce

1. Configure a DVCS account in Jira
2. Perform synchronizations that take a long time

Expected Results

Up to dvcs.connector.synchronization.threads_per_consumer threads should perform the synchronization

Actual Results

Only one thread is performing the synchronization. This is evident by looking at thread dumps as well as log outputs for MessageExecutor:thread-1, and never thread-2 for example.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
