	/**
	* Convert any collection to a map by iterating over its contents
	* and taking a result of the entry as the key to the map. The

	* in the collection, or may be a string identifying the property
	* to act as the key for each entry.

	def future = executor.submit((java.util.concurrent.Callable) {
	'TEST'
	})

	assert('TEST' == future.get())
