If name of database table is written in small letters Artemis can't detect its existence ---------------------------------------------------------------------------------------- Key: WFLY-8307 URL: https://issues.jboss.org/browse/WFLY-8307 Project: WildFly Issue Type: Bug Components: JMS Environment: Oracle 12c database Reporter: Jeff Mesnil Assignee: Jeff Mesnil Priority: Critical If the name of database table is written in small letters - e.g. node1_messages_table, Artemis can't detect its existence and it tries to create it again what leads to error \[1\]. This happens after restarting of server. I don't see the issue if name of database table is written in capital letters - e.g. NODE1_MESSAGES_TABLE. \[1\] {code} 14:00:26,208 ERROR

impact:* If names of database tables are written in small letters, EAP fails at second start. From logs it's not easy to find out what is wrong and how workaround the issue. It is serious user experience problem.
