I haven't managed to reproduce this on WildFly, it seems to be working just fine,
albeit by chance as ordering is 'random' without priority.
Would you mind giving the fix a spin and tell me if it works for you? Better safe than
The PR is here -

Actually, in CDI 2.0 you can use @Priority to order observer methods - we
could add @Priority(0) to ProbeExtension to ensure it goes first and avoid
such possible clashes.
As for temporary workaround, you can exclude FacesConfigBeanHolder (the
invoked bean) from monitoring to avoid triggering Probe too early.
You can do that via `org.jboss.weld.probe.invocationMonitor.excludeType`
property as described in Weld docs -
