bq. In fixed-delay execution, each execution is scheduled relative to the
actual execution time of the previous execution. If an execution is delayed for
any reason (such as garbage collection or other background activity),
subsequent executions will be delayed as well. [0]
bq.
I no longer get this behavior unless I use synchronous=true. In prior versions,
the delay period began after the previous execution completed.
Edit: This could be because I used to use the salesforce synchronous=true
option. More evidence that any async operation on a route could cause the timer
thread to return immediately, thus starting the delay period.

> Noticed a different behaviour of Camel timer with 3.5.0 when compared with
> Camel version 2.24.3. In 3.5.0. Camel timer fires events as if it is
> fixedRate is true (even if I explicitly make it false in the Camel URL).

> I am attaching sample code for 3.5.0 version.
