//The easy way is to just read in the entire message in memory, parse it from JSON into an object, and then return a message for each encounter:


var queue = $gc('queue');
if (!queue) {
	queue = new java.util.LinkedList();
	var obj = JSON.parse(org.apache.commons.io.IOUtils.toString(reader));
	for each (encounter in obj.encounterList) {
		queue.add(JSON.stringify(encounter));
	}
	$gc('queue', queue);
}

var message = queue.poll();
if (!message) {
	globalChannelMap.remove('queue');
}
return message;
