| 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. | ||
