As described in the title, this is a simple change to the `HttpRequest.Builder::build` method to highlight that an immutable and reusable instance of an `HttpRequest` is created when this method is invoked. This is done by adding an `@implSpec` Javadoc Tag (details on `@implSpec` given [here](https://openjdk.java.net/jeps/8068562)).
The detail added under the `@implSpec` Tag is similar to that provided at the interface-level Javadoc for Builder. Please also review the CSR for this change: https://bugs.openjdk.java.net/browse/JDK-8281833 ------------- Commit messages: - 8281223: Improve the API documentation of HttpRequest.Builder::build to state that the default implementation provided by the JDK returns immutable objects.
