not starting with graylog 5.1

[Marc Diesse]

The plugin fails to start with graylog 5.1. It logs the following error:

1) [Guice/MissingImplementation]: No implementation for MQTTGELFInput$Factory was bound.

Requested by:
1  : Graylog2Module.installInput(Graylog2Module.java:233)
      \_ installed by: PluginBindings -> MQTTInputModule

2) MessageInput$Descriptor is abstract, not a concrete class.  Unable to create AssistedInject factory.
  while locating MessageInput$Descriptor
  at MessageInput$Factory.getDescriptor(MessageInput.java:1)

It can be reproduced with the following docker-compose file (volume and plugin paths need to be adjusted):

Can this be solved by building with newer java version?
