AMQ broker with JDBC persistence store leaks records in messaging table. When I send 1000 messages to the broker I can see 400 rows in the table:

jbossdb=# select count from message_tbl ;
count
-------
4000
(1 row)
jbossdb=#

After consuming all message I would expect to see the table empty but this is not the case. I see 2000 rows:

jbossdb=# select count from message_tbl ;
count
-------
2000
(1 row)
jbossdb=# 

 
If I repeat the above I see another 200 rows after all messages have been consumed. It looks to me like for each consumed message two rows are added to the table. As far as I can tell those rows are never deleted.
