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.
