- * AWT native interface (new in JDK 1.3)
- *
- * The AWT native interface allows a native C or C++ application a means
- * by which to access native structures in AWT.  This is to facilitate moving
- * legacy C and C++ applications to Java and to target the needs of the
- * community who, at present, wish to do their own native rendering to canvases
- * for performance reasons.  Standard extensions such as Java3D also require a
- * means to access the underlying native data structures of AWT.
- *
- * There may be future extensions to this API depending on demand.
- *
- * A VM does not have to implement this API in order to pass the JCK.
- * It is recommended, however, that this API is implemented on VMs that support
- * standard extensions, such as Java3D.
- *
- * Since this is a native API, any program which uses it cannot be considered
- * 100% pure java.
