Nit - Would it better to reword this as:

> // Exceptions are often thrown from asynchronous code, and the 
// stacktrace may not always contain the application classes.
// That makes it difficult to trace back to the application code which
// invoked the HttpClient. Here we instantiate/recreate the
// exceptions to capture the application's calling code in the
// stacktrace of the thrown exception.
