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

Cannot reproduce this on master branch from an unit test in camel-jms, and also with using load testing via http server from undertow and AB testing via hey.

> Reported on an older Camel 2.x version but there is a potential problem when a new JmsEndpoint / JmsProducer is created via toD and it creates a JmsInOnlyTemplate that seems to have a race condition causing a NPE in ConnectionFactory.
> Using toD("jms:queue:${property.queuename}) in a route which normally works fine but under high load it sometimes fails with:
> (stacktrace for Camel 2.x)
> java.lang.IllegalArgumentException: connectionFactory must be specified
