> Key: WFWIP-279
> URL: https://issues.redhat.com/browse/WFWIP-279
> Project: WildFly WIP
> Issue Type: Bug
> Components: MP Config
> Reporter: Ivan Straka
> Assignee: Jeff Mesnil
> Priority: Blocker

> I have a fail safe service that would normally return a value provided by a provider A or a value from provider B on fallback (in case the provider A throws an exception). Providers return values based on MP Config property. Source of the properties is a ConfigSource class that reads a property file.
> The issue is ConfigSource#getProperties method is called too may times that results to Too many open files exception:
