Spring Async method or event throws HystrixRequestContext.initializeContext() exception
<p>Our code has a few @Async methods, and ApplicationListeners. These classes and methods end up calling API services that have the @Hystrix annotation. These calls throw the following exception:</p>

<pre><code>java.lang.IllegalStateException: HystrixRequestContext.initializeContext() must be called at the beginning of each request before RequestVariable functionality can be used.

<p>Adding HystrixRequestContext.initializeContext() in the Async method does not help.</p>
