As i had suspected the sql statement that creates the timers table was the culprit. The statement is actually dynamically built in a java class called GenericDatabasePersistencePlugin. This bug has been fixed as of jboss 4.0.5. On a side note we ran into another issue that had to do with creating hilosequences table and for that the culprit was the jboss-service.xml present in the uuid*generator*.sar. The xml file had the DDL to create the table and the DDL was again incorrect for IDS. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993515#...
