When the messaging service starts, it runs the DDL statements to create the tables it needs. If these fail because the tables already exist, you get these DEBUG log entries. I can think of two ways to turn them off: 1) Change the code to not log the messages 2) Change the logging level to INFO for the messaging loggers. And to answer you other question, yes most people running JBoss AS simply ignore these log entries. In general, if the stack trace does not show up in the console log, it is OK to ignore.
