> Blueprint testing - Potential dead lock
> ---------------------------------------

> Key: CAMEL-5307
> URL: https://issues.apache.org/jira/browse/CAMEL-5307

> Issue Type: Task
> Components: camel-test
> Affects Versions: 2.10.0
> Reporter: Claus Ibsen
> Fix For: 2.10.0
>
>
> Using the camel-test-blueprint, there is a potential dead-lock as namespace
> parser and main method is separate threads, and the namespace parser may
> still run, when main thread starts the test.
