[BUG] ClassNotFoundException: io.streamnative.pulsar.handlers.amqp.authentication.AuthenticationProviderBasic

[emmanuelGuiton]

Describe the bug
I am trying to configure Basic AMQP authentication using apachepulsar/pulsar
Docker image + AoP. I can successfully install the protocol handler. When I register the io.streamnative.pulsar.handlers.amqp.authentication.AuthenticationProviderBasic provider in the standalone.conf authenticationProviders=org.apache.pulsar.broker.authentication.AuthenticationProviderBasic,io.streamnative.pulsar.handlers.amqp.authentication.AuthenticationProviderBasic I get a ClassNotFoundException :

What am I doing wrong ?

To Reproduce
Steps to reproduce the behavior:

1. Write a Dockerfile to install the AoP NAR file in the apachepulsar/pulsar image
2. Add io.streamnative.pulsar.handlers.amqp.authentication.AuthenticationProviderBasic to the authenticationProviders parameter in the standalone.conf file.
3. Run the image with the command bin/pulsar standalone
4. Look for the error in the logs.

Expected behavior
The basic authentication provider for AMQP should register successfully.

Additional context
Using Pulsar 2.11.0 and AoP 2.11.0.3

Note that the result is the same when I use the streamnative/sn-pulsar:2.10.3.6 image instead of building a custom image with only the AoP plugin.

Well, I finally noticed that the io.streamnative.pulsar.handlers.amqp.authentication.AuthenticationProviderBasic class does not exist in version 2.10.x . So my second comment is pointless.
