  * While the RabbitMQ tutorial for using with the dockerized RabbitMQ setup
  * correctly and loads the PhpAmqpLib\\Channel\\AMQPChannel class in time for
  * the agent to wrap the instrumented functions, there are AWS MQ_BROKER
  * specific but valid scenarios where the PhpAmqpLib\\Channel\\AMQPChannel class
  * file does not explicitly load or does not load in time, and the instrumented
  * functions are NEVER wrapped regardless of how many times they are called in
  * one txn.  Specifically, this centered around the very slight but impactful
- * differences when using the PhpAmqpLib\Connection\AMQPStreamConnection which
+ * differences when using managing the AWS MQ Broker connect vs
  * causes an explicit load of the AMQPChannel class/file and
  * PhpAmqpLib\Connection\AMQPSSLConnection which does NOT cause an explicit load
  * of the AMQPChannelclass/file. The following method is thus the only way to
  * ensure the class is loaded in time for the functions to be wrapped.
