> In VertexManager constructor, we create VertexManagerPlugin before initializing user payload. 
> {code:java}
> plugin = ReflectionUtils.createClazzInstance(pluginDesc.getClassName(),
>         new Class[] { VertexManagerPluginContext.class }, new Object[] { pluginContext });
>     payload = pluginDesc.getUserPayload();
> {code}
> Trying to access user payload in VertexManagerPlugin constructor will result in a NullPointerException.
