PubSub runs into `java.lang.RuntimeException: ManagedChannel allocation site` when a new publisher is created

See original GitHub issue

Hi!

We’ve currently received around 100-200 PubSub related issues when a PubSub publisher is created with the following stacktrace:

io.grpc.internal.ManagedChannelOrphanWrapper$ManagedChannelReference cleanQueue: *~*~*~ Channel ManagedChannelImpl{logId=4613, target=pubsub.googleapis.com:443} was not shutdown properly!!! ~*~*~* (ManagedChannelOrphanWrapper.java:163)
    Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

We are using PubSub library v 1.40.0. And here is how we create publishers:

Publisher createPublisher(ProjectTopicName topicName) {
        try {
            Publisher publisher = Publisher.newBuilder(topicName)
                                           .build();
            return publisher;
        } catch (IOException e) {
            String errorMessage = format("Cannot create a publisher for topic %s", topicName);
            throw new IllegalStateException(errorMessage, e);
        }
    }

Any thoughts or suggestions? By the way, we are running on AppEngine Standard with Java 8.

Yeah, we do still experience problems.

We are also using 1.48.0 now.
