JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

     * for example, in order to provide a progressive display effect,
     * or perform other incremental processing.
     *
     * <p> Note that different image format readers may produce
     * decoded pixels in a variety of different orders.  Many readers
     * will produce pixels in a simple top-to-bottom,
     * left-to-right-order, but others may use multiple passes of
     * interlacing, tiling, etc.  The sequence of updates may even
     * differ from call to call depending on network speeds, for
     * example.  A call to this method does not guarantee that all the
     * specified pixels have actually been updated, only that some
     * activity has taken place within some subregion of the one
     * specified.
     *
     * <p> The particular <code>ImageReader</code> implementation may
     * choose how often to provide updates.  Each update specifies
     * that a given region of the image has been updated since the
     * last update.  A region is described by its spatial bounding box
     * (<code>minX</code>, <code>minY</code>, <code>width</code>, and
     * <code>height</code>); X and Y subsampling factors
     * (<code>periodX</code> and <code>periodY</code>); and a set of
     * updated bands (<code>bands</code>).  For example, the update:
     *
     * <pre>
     * minX = 10
     * minY = 20
     * width = 3
     * height = 4

     * periodY = 3
     * bands = { 1, 3 }
     * </pre>
     *
     * would indicate that bands 1 and 3 of the following pixels were
     * updated:
     *
     * <pre>
     * (10, 20) (12, 20) (14, 20)
