Hello camel gurus,

I just need some clarification about how DefaultEndpoint, DefaultProducer 
behave depends on whether their isSingleton method returns true or false.

My understanding is the follosing:


1.       If DefaultEndpoint.isSingleton() returns true the same instance of the 
endpoint will be reused across all the camel contexts, and in case of OSGi this 
mean that the same endpoint instance will be reused across all the bundles that 
contain some camel functionality.

2.       If DefaultEndpoint.isSingleton() returns false then for each camel 
context a new instance of the endpoint is created and in the OSGi the new 
instance of the endpoint will be created for each separate bundle that contains 
a camel context.

3.       If DefaultProducer.isSingleton() returns true then the same instance 
of the producer, i.e., will be used every time not depending on the endpoint 
uri, i.e. for the following producers <to uri=”comp:producer?param1=val1”/> and 
<to uri=”comp:producer?param1=val1&param2=val2”/> will be used the same 
instance of the producer?

4.       If DefaultProducer.isSingleton() returns false then for the different 
endpoint URIs will be returned different instances of producer.

So summarizing all the points above if DefaultEndpoint.isSingleton() is true 
and DefaultProducer.isSingleton() in the OSGi environment then the producers 
will be shared across all the camel contexts located in all the OSGi bundles, 
right?


Best Regards,
Sergey
