[reload4j] org.apache.log4j.jmx missing in v.1.2.19

Hello, I am trying to replace log4j1 with reload4j v.1.2.19 and found that the org.apache.log4j.jmx package is not there any more. Our code cannot compile because it uses the jmxHierarchyDynamicMBean. I wonder if it's available in other artificats. If not, would it be possible to add them back? Thanks, Li
