Search before asking

• I searched in the issues and found nothing similar.

Read release policy

• I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

Version

master

Minimal reproduce step

Modify cleanup in InmemoryTopicPoliciesServiceServiceTest and run it. This will timeout:

    @AfterClass
    @Override
    protected void cleanup() throws Exception {
        admin.brokers().shutDownBrokerGracefully(0, false)
                .get(15, TimeUnit.SECONDS);
        super.internalCleanup();
    }

What did you expect to see?

The broker should be able to shutdown using the graceful shutdown API.

What did you see instead?

The shutdown timed out.

Anything else?

The shutdown times out.
