Thanks for the report, @ennishol. Could you please share a minimal reproducer project?

[jamesnetherton]

It's easy to reproduce just by adding the quartz extension to any of our existing example projects.

You can add camel-quarkus-cron as a workaround. E.g:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-cron</artifactId>
    <version>1.0.0-M7</version>
</dependency>

I'll work on a permanent fix to try and avoid this.
