/**
 * Simple wrapper exception that you can use when you want the error handling system to handle the
 * {@link WrapperException#getCause()} of this instance rather than this instance itself, but still log the entire
 * stack trace (including this instance). This is often necessary in asynchronous scenarios where you want to add
 * stack trace info for the logs but don't want to obscure the true cause of the error.
