CAMEL-11977: MongoDB Tailable cursor consumer fails to stop on shutdown
cursor.hasNaxt() locks thread and waits for new object. Camel mongodb
component uses loop to get new cursor objects, so we can just try if next is
present without waiting for new object. tryNext() is what we need in this casre.
According to mongoBD documentation:
[](http://api.mongodb.com/java/current/com/mongodb/client/MongoCursor.html)
tryNext() A special next() case that returns the next element in the
iteration if available or null.
So after exit hook injection. when java will call
MongoDbTailingProcess.stop(), there will be no lock at
MongoDbTailingProcess.run(). so MongoDbTailingProcess instance will be stopped.
