Getting java.sql.SQLException: ISAM error: record is locked in JBoss EAP 6

Issue

• Daily we have to restart the JBoss from a scheduled task. JBoss shuts down but does not start. So, we start it manually. We're getting the below error:

Caused by: java.sql.SQLException: Could not do a physical-order read to fetch next row.
