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.

/**
 * An object used in <code>Request</code> operations
 * to specify the context object in which context strings
 * must be resolved before being sent along with the request invocation.
 * A <code>Context</code> object
 * contains a list of properties in the form of <code>NamedValue</code>
 * objects. These properties represent information
 * about the client, the environment, or the circumstances of a request
 * and generally are properties that might be inconvenient
 * to pass as parameters.
 * <P>
 * A <code>Context</code> object is created by first calling the
 * <code>ORB</code> method <code>get_default_context</code>
 * and then calling the method <code>create_child</code> on the
 * default context.
 * <P>
 * Each property in a <code>Context</code> object is represented by
 * a <code>NamedValue</code> object.  The property name is contained
 * in the <code>NamedValue</code> object's <code>name</code> field, and
 * the value associated with the name is contained in the <code>Any</code>
 * object that was assigned to the <code>NamedValue</code> object's
 * <code>value</code> field.
 * <P>
 * <code>Context</code> properties can represent a portion of a client's
 * or application's environment that is meant to be propagated to
 * (and made implicitly part of) a server's environment.
 * (Examples might be a window identifier or user preference information).
 * Once a server has been invoked (that is, after the properties are
 * propagated), the server may query its <code>Context</code> object
 * for these properties using the method <code>get_values</code>.
 *
 *<P>
 * When an operation declaration includes a context clause,
 * the stubs and skeletons will have an additional argument
 * added for the context.  When an operation invocation occurs,
 * the ORB causes the properties that were named in the operation
 * definition in IDL and
 * that are present in the client's <code>Context</code> object
 * to be provided in the <code>Context</code> object parameter to
 * the invoked method.
 * <P>
 * <code>Context</code> property names (which are strings)
 * typically have the form of an OMG IDL identifier or
 * a series of OMG IDL identifiers separated by periods.
 * A context property name pattern is either a property name
 * or a property name followed by a single "*".  A property
 * name pattern without a trailing "*" is said to match only
 * itself.  A property name pattern of the form "&lt;name&gt;*" matches any
 * property name that starts with &lt;name&gt; and continues with zero
 * or more additional characters.
 * <P>
 * Property name patterns are used in the context clause of
 * an operation definition and as a parameter for the
 * method <code>Context.get_values</code>.
 * <P>
 * <code>Context</code> objects may be "chained" together to achieve a
 * particular defaulting behavior.  A <code>Context</code>
 * object created with the method <code>create_child</code> will
 * be chained to its parent (the <code>Context</code> object
 * that created it), and that means that the parent will be searched
 * after the child in a search for property names.
 *<P>
 * Properties defined in a particular <code>Context</code> object
 * effectively override those properties in the next higher level.
 * The scope used in a search for properties may be restricted by specifying a
 * starting scope and by using the flag <code>CTX_RESTRICT_SCOPE</code>
 * when invoking the method <code>get_values</code>.
 * <P>
 * A <code>Context</code> object may be named for purposes of specifying
 * a starting search scope.
