When creating an issue, JIRA hangs. The last message in the logs is:

[INFO] StoreFactory - -Initializing WorkflowStore: com.opensymphony.workflow.spi.ofbiz.OfbizWorkflowStore^M

After a log time, the following exception may print in the logs:

ENTRY_ID, STEP_ID, ACTION_ID, OWNER, START_DATE, DUE_DATE, FINISH_DATE, STATUS, CALLER) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
