ThreadLocal memory leak in HystrixRequestContext

[jrummler]

When shutting down Tomcat with registered HystrixRequestContextServletFilter there seems to be a memory leak detected when shutting the context down:

2014-09-25 16:17:47,774 SEVERE -  - org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks - The web application [/someWebApp] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@5e99af68]) and a value of type [com.netflix.hystrix.strategy.concurrency.HystrixRequestContext] (value[com.netflix.hystrix.strategy.concurrency.HystrixRequestContext@2685b544]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

However, I call Hystrix.reset() when shutting down - is there anything I can do but deactivate memory leak checks on Tomcat shutdown?

Thank you!

I don't know. We never shut apps down gracefully, we just kill the process.

Is there anything further to do on this?
