JRE 8 rt.jar - java.* Package Source Code
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.
JAR File Information:

Other mechanisms may be added in the future. In * beans 1.0 we first try to treat the beanName as a serialized object * name then as a class name. * <p> * When using the beanName as a serialized object name we convert the * given beanName to a resource pathname and add a trailing ".ser" suffix. * We then try to load a serialized object from that resource. * <p> * For example, given a beanName of "x.y", Beans.instantiate would first * try to read a serialized object from the resource "x/y.ser" and if * that failed it would try to load the class "x.y" and create an * instance of that class. * <p> * If the bean is a subtype of java.applet.Applet, then it is given * some special initialization. First, it is supplied with a default * AppletStub and AppletContext. Second, if it was instantiated from * a classname the applet's "init" method is called. (If the bean was * deserialized this step is skipped.) * <p> * Note that for beans which are applets, it is the caller's responsiblity * to call "start" on the applet. For correct behaviour, this should be done * after the applet has been added into a visible AWT container. * <p> * Note that applets created via beans.instantiate run in a slightly * different environment than applets running inside browsers. In * particular, bean applets have no access to "parameters", so they may * wish to provide property get/set methods to set parameter values.
