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.

 * LayoutPath provides a mapping between locations relative to the

 * along the baseline, and an offset perpendicular to the baseline at
 * the advance.  Positive values along the perpendicular are in the
 * direction that is 90 degrees clockwise from the baseline vector.
 * Locations are represented as a <code>Point2D</code>, where x is the advance and
 * y is the offset.
