  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 (for example,
  44      *  "Toolkit"s/Peer), such as Motif, Microsoft Windows, 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.
