In jboss-logging.xml, uncomment the SMTP section and add a property "threshold" in either of the 2 ways:

<property name="threshold">ERROR</property>

<property name="threshold" class="org.apache.log4j.Priority">ERROR</property>

(This property is added here just for testing purpose.)

Either way results in the following error at startup. It appears the property values are always considered as string even with the class specified. Is there a fix or workaround for this?
