When I'm trying to use TransactionMonitor with the following code:

		TransactionMonitor txnmonitor = new TransactionMonitor(getClass(), "sometexthere", MonitoringLevel.INFO);
                ...
		txnmonitor.succeeded();
		txnmonitor.done();

I get the following exception:

[MonitoringEngine:623] [class com.orbitz.monitoring.api.monitor.TransactionMonitor attributes={sequenceId=m, threadId=11768ab, createdAt=Thu Sep 04 15:11:07 WAT 2008, name=[some.secret.here]}level=INFO] will be processed by [com.orbitz.monitoring.lib.processor.AsyncMonitorProcessor@1cc4e47]

The _childMonitors member seems to be null.
