Concurrent access leads to empty domain.xml

Hi Red Hat team. We're still trying to narrow down the trigger but there is a very serious bug when using the admin console in AS 7.1 Final that causes the domain.xml file to be wiped of everything other than the extensions section that is at the top. Have not checked yet if this is a known bug or not but wanted to alert you immediately.

The potential trigger for this is more than one person using the admin
console at the same time. Even if just for monitoring while the other
person is making configuration changes. (Fortunately we had backed up
the config using the CLI.)

We are trying right now to get our QA1 drop out the door but we'll be
giving this a closer look tomorrow. Has anyone else reported this though?

Thanks,
Bill
