-----------------------------------

             Summary: camel-core - The local properties of the properties 
component should be per thread
                 Key: CAMEL-25112
                 URL: https://issues.apache.org/jira/browse/CAMEL-25112
             Project: Camel
          Issue Type: Improvement
          Components: camel-core
            Reporter: Claus Ibsen


The local properties of the properties component (such as the parameters of a 
route template, used while creating a route from the template) are kept in a 
single stack that is shared by all threads (since CAMEL-21675), while the 
javadoc says they are local for the current thread. Camel starts routes in a 
thread safe way itself, but to prepare for adding routes dynamically from 
multiple threads, the local properties should be per thread.

Also:
* When starting routes, the local properties are removed after each route, also 
for a route that did not add any (a route that is not from a route template), 
which removes local properties added by the caller.
* camel-main configures {{camel.aiObservability.enabled}} as a local property 
(that is never removed). As it is removed when the routes are started (see 
above), and is not seen by other threads, the setting is lost, so 
{{aiObservability().withEnabled(false)}} does not disable GenAI observability 
when there are routes. The setting is now configured as an override property.
