FaultTolerance subsystem gets MP Config properties values too many times ------------------------------------------------------------------------ Key: WFWIP-279 URL: https://issues.redhat.com/browse/WFWIP-279 Project: WildFly WIP Issue Type: Bug Components: MP Config, MP Fault Tolerance Reporter: Ivan Straka Assignee: Radoslav Husar 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: {code:java} 13:41:48,959 ERROR [stderr] (MSC service thread 1-4) java.io.FileNotFoundException:
