In Liferay Connected Services in osb-lcs-portlet we have decalred three scheduled listeners:

<scheduler-entry>
			<scheduler-event-listener-class&gt;com.liferay.osb.lcs.notifications.messaging.ReorganizeLCSDealsServersUsedMessageListener</scheduler-event-listener-class&gt;
			<trigger>
				<simple>
					<simple-trigger-value>1</simple-trigger-value>
					<time-unit>minute</time-unit>
				</simple>
			</trigger>
		</scheduler-entry>
		<scheduler-entry>
			<scheduler-event-listener-class&gt;com.liferay.osb.lcs.notifications.messaging.CheckStaleLCSRolesMessageListener</scheduler-event-listener-class&gt;
			<trigger>
				<simple>
					<simple-trigger-value>1</simple-trigger-value>
					<time-unit>minute</time-unit>
				</simple>
			</trigger>
		</scheduler-entry>
		<scheduler-entry>
			<scheduler-event-listener-class&gt;com.liferay.osb.lcs.notifications.messaging.CheckStaleLCSInvitationsMessageListener</scheduler-event-listener-class&gt;
			<trigger>
				<simple>
					<simple-trigger-value>1</simple-trigger-value>
					<time-unit>minute</time-unit>
				</simple>
			</trigger>
		</scheduler-entry>

Just one listener is being scheduled properly:

com.liferay.osb.lcs.notifications.messaging.CheckStaleLCSRolesMessageListener

Other two listeners are never invoked.
If listeners:

com.liferay.osb.lcs.notifications.messaging.CheckStaleLCSInvitationsMessageListener
com.liferay.osb.lcs.notifications.messaging.ReorganizeLCSDealsServersUsedMessageListener

are renamed to shorter class name, they are properly scheduled and working as expected.
HINT: I went through code and got impression that if listener name is too long,

com.liferay.portal.kernel.messaging.proxy.ProxyMessageListener

receives ProxyRequest wrongly configured in payload, instead of schedule method, it invokes toString method on QuartzSchedulerEngine.
Please be aware that there is chance I wrongly interpreted my stack state while debugging.
