CircuitBreakerOpenException get reason

[Phillip Krüger]

Hi all.

In the Fault Tolerance Api, when a circuit breaker activates, a  CircuitBreakerOpenException gets thrown. Is there a way to get the original reason that the circuit has been tripped from the CircuitBreakerOpenException ?

CircuitBreakerOpenException.getCause seems to be null ? (wildfly-swarm at least)

Thanks

Phillip,

If you've found an issue with the WF Swarm implementation of Eclipse FT, please raise an issue here: https://issues.jboss.org/projects/THORN/issues/THORN-2031?filter=allopenissues

Thanks

Hi Ken

Thanks for the reply. I will definitely do that (maybe even with a pull request :) ). I just want to confirm that this should be possible. (So what does the spec say ?)

Should I be able to get the 'reason' the switch tripped in the CircuitBreakerOpenException ? I can not see much in the spec:

http://microprofile.io/project/eclipse/microprofile-fault-tolerance/spec/src/main/asciidoc/circuitbreaker.asciidoc

I'll look at the wildfly-swarm (or thorntail) code so long and see if it's possible. Maybe the spec authors can comment on what the behaviour should be?

Thanks again!
