-----------------------------------

Hmm... Sorry I should have mention that it is when executing "undeploy" (or shutdown) as the problem shows as a warning.

Why does the JMX impl. in JBoss 7 always try to inject NULL values into configured MBean attributes at undeployment?

> Using "attribute" tag in "jboss-service.xml" in a SAR archive causes injection of null values. Even if your code can handle this it makes it impossible to use primitive datatypes.
