/**
* A customized version of the default {@link CommandInvoker} for use with CDI.
*
* The Flowable-CDI integration builds upon the availability of the current execution in a thread local 'execution context'. As this has a (very minimal) impact on performance, this thread local is
* not set by the default {@link CommandInvoker} and thus this customized version is needed.
