-   *
-   * Object.<clinit> uses a String literal, possibly triggering initialization

-   *  System.loadLibrary calls Runtime.getRuntime, triggering initialization
-   *   Runtime.<clinit> calls Properties.<init>, triggering initialization
-   *    Dictionary, Hashtable, and Properties have no dependencies
-   *   Runtime.<clinit> calls VMRuntime.insertSystemProperties, triggering
-   *      initialization of VMRuntime; the VM must make sure that there are
-   *      not any harmful dependencies
-   *   Runtime.<clinit> calls Runtime.<init>
-   *    Runtime.<init> calls StringTokenizer.<init>, triggering initialization
-   *     StringTokenizer has no dependencies
-   *  System.loadLibrary calls Runtime.loadLibrary
-   *   Runtime.loadLibrary should be able to load the library, although it
