Since HTTP requests frequently happen in parallel, connection pooling must be thread-safe.

These are the primary classes involved with establishing, sharing, and terminating connections:

 * **RealConnectionPool** manages reuse of HTTP and HTTP/2 connections for reduced latency. Every OkHttpClient has one, and its lifetime spans the lifetime of the OkHttpClient.

     * For most deterministic builds, the array length should be 1. In such case,
     * the dependency will be unconditionally placed on the specified type of path
     * and no heuristic rule will be involved.
     *
     * <p>It is nevertheless common to specify two or more types of path. For example,
     * a Java library may be compatible with either the class path or the module path,

 * Utility class for method operations.
