I've encountered some problems regarding starting Camel. I use Camel 2.5.0.
I also use iPOJO in Karaf to create OSGi services. When my iPOJO instance
becomes valid, my callback method is started and I try to create a Camel
context and start it.
However, even if I fail to start Camel, no exception is thrown which causes
me problems later on. When looking through the code it seems like an
exception is caught but not rethrown in DefaultCamelContext.doStartCamel()
on line 1270. Is this "as designed" or a bug? I would really like an
exception to be thrown at this point to allow me to know whether I succeeded
in starting the context or not.
In my particular case, I have erroneously set the name of the camel context
to null.
The exception I get is the following:
