JBoss Data Virtualization getting JdbcSQLException: Database may be already in use: "Locked by another process"

Issue

• After updating JBoss Data Virtualization from 6.2.0 to 6.2.6 I am seeing multiple exception messages in the log.

• When I delete the file teiid-dashboard-ds.lock.db it immediately gets recreated even though I have stopped JBoss Data Virtualization.

• Getting the following exceptions in server.log:
