When changing configuration of Audit and Command logging via Web Management, an exception is thrown in specific usecase, see the steps to reproduce below.
Then even after server restart logging doesn't work. No changes noticed in standalone.xml during the configuration.

Version-Release number of selected component (if applicable):
DV 6.1.0 ER4

How reproducible:
Once after installation (further on the logging simply doesn't work)

Steps to Reproduce:
1.Install DV with audit/command logging enabled
2.Start DV with bin/standalone.sh, check that logging works
3.Access http://localhost:9990/console/App.html#teiid-audit and unselect selected options
4.Apply
5.Select the previously deselected options again
6.Apply
7.See the server log in console
8.When there is server reload between unselecting and reselecting the options, then the exception is not raised, but the logging doesn't work afterwards.

Actual results:
java.lang.IllegalArgumentException: Handler "TEIID_AUDIT_LOG" is not found
or
java.lang.IllegalArgumentException: Handler "TEIID_COMMAND_LOG" is not found

Expected results:
Logging configured again
