HystrixPlugins Another strategy was already registered.

[Ruddy32]

Hi,

While running unit test, I get the following exception :

Caused by: java.lang.IllegalStateException: Another strategy was already registered.
    at com.netflix.hystrix.strategy.HystrixPlugins.registerConcurrencyStrategy(HystrixPlugins.java:190)
    at io.smallrye.faulttolerance.HystrixInitializer.onStartup(HystrixInitializer.java:54)
    ... 28 more

Is there missing configuration file?

Is it possible to remove faulttolerance service?

Thanks,

Ruddy32

You can remove MP Fault Tolerance by excluding the dependency, if you've added the all encompassing "microprofile" dependency.

I've never seen this error before.

Do you have an example repo you can share?

The repository is available at https://github.com/ruddy32/thorntail-deltaspike.

I fix the problem by removing Fault Tolerence dependency.

This issue is register in https://github.com/Netflix/Hystrix/issues/1057. I don't dig to find a solution. Is there a minimum configuration to provide in the application ?

It looks like a Hystrix command is executed before CDI is initialized
and SmallRye FT concurrency strategy is registered.

How do I reproduce the problem? What test should I run?
