Interface PropertiesMonitorMBean

All Superinterfaces:

SelfEmailingMBean

public interface PropertiesMonitorMBean
extends SelfEmailingMBean

Exposes current properties settings

This is necessary in part because Sun's java.lang:type=Runtime MBean currently has a bug where if anyone has called System.setProperties() with a Properties object that has been constructed via new Properties( System.getProperties() ) only the non-default values are shown by the SystemProperties attribute. Additionally, the SystemProperties attribute is a CompositeData attribute and some consoles (like jconsole currently) show this data in hash (rather than sorted) order.
