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

> camel-jms - toD under heavy load can cause NPE when connection factory
> configured on JMS component level

> Key: CAMEL-15985
> URL: https://issues.apache.org/jira/browse/CAMEL-15985
> Project: Camel
> Issue Type: Bug
> Components: camel-jms
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 3.8.0
>
>
> 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
> at org.apache.camel.util.ObjectHelper.notNull(ObjectHelper.java:321)
