31     * This is copied from java.awt.Toolkit since we need the library
32     * loaded in sun.awt.image also:
33     *
34     * WARNING: This is a temporary workaround for a problem in the
35     * way the AWT loads native libraries. A number of classes in this
36     * package (sun.awt.image) have a native method, initIDs(),
37     * which initializes
38     * the JNI field and method ids used in the native portion of
39     * their implementation.
40     *
41     * Since the use and storage of these ids is done by the
42     * implementation libraries, the implementation of these method is
43     * provided by the particular AWT implementations
44     * (i.e. "Toolkit"s/Peer), such as Motif, Win32 or Tiny. The
45     * problem is that this means that the native libraries must be
46     * loaded by the java.* classes, which do not necessarily know the
47     * names of the libraries to load. A better way of doing this
48     * would be to provide a separate library which defines java.awt.*
49     * initIDs, and exports the relevant symbols out to the
50     * implementation libraries.
51     *
52     * For now, we know it's done by the implementation, and we assume
53     * that the name of the library is "awt".  -br.
