API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
issue if there is one) requesting the feature and describing specific use cases
for it.

If the feature has merit, it will go through a thorough process of API design

            throw new CIFSException("Failed to create channels for session " + sessionId, e);
        }
    }

    /**
     * Selects the best channel for an operation.
     *
     * @param sessionId the session identifier
     * @return the selected channel, or null if no channels available
     */
    public ChannelInfo selectChannel(String sessionId) {

        } catch (NullPointerException e) {

   * building caches whose key or value types are incompatible with the types accepted by the
   * weigher already provided; the {@code CacheBuilder} type cannot do this. For best results,
   * simply use the standard method-chaining idiom, as illustrated in the documentation at top,
   * configuring a {@code CacheBuilder} and building your {@link Cache} all in a single statement.

    connection reuse.

 *  Breaking: Replace our parameters-based JUnit 5 extension with a new annotation, `@StartStop`.
    Put this annotation on a `MockWebServer` property and the extension will start it before your
    test executes and stop it after it completes. No further configuration is required.

    ```kotlin
    @StartStop val server = MockWebServer()
    ```
