> In VertexManager constructor, we create VertexManagerPlugin before initializing user payload.
> {code:java}
> plugin = ReflectionUtils.createClazzInstance(pluginDesc.getClassName(),
> new Class[] { VertexManagerPluginContext.class }, new Object[] { pluginContext });

> {code}
> Trying to access user payload in VertexManagerPlugin constructor will result in a NullPointerException.
