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.
