Looks like executor is null there which indicates that there is a race
condition between bind and activate.
{code}
protected void activate(ComponentContext context, Map<String, ?> config)
throws Exception {
this.context = context;
whiteboard = new OsgiWhiteboard(context.getBundleContext());
executor = new WhiteboardExecutor();
executor.start(whiteboard);
{code}
We should initialize executor before context. This would ensure by the time
registerNodeStoreIfPossible proceeds to registerNodeStore executor is
initialized
