PicketLink IDM throwing error org.hibernate.TransactionException: Transaction not successfully started

Issue

When there is a DB issue like java.sql.SQLRecoverableException: No more data to read from socket and login fails in IDM, the same thread will keep throwing org.hibernate.HibernateException: flush is not valid without active transaction so login will keep failing even after the DB is recovered.
