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.

/**
 * Class ReferenceUriSchemesSupported is a printing attribute class
 * an enumeration, that indicates a "URI scheme," such as "http:" or "ftp:",
 * that a printer can use to retrieve print data stored at a URI location.
 * If a printer supports doc flavors with a print data representation class of
 * <CODE>"java.net.URL"</CODE>, the printer uses instances of class
 * ReferenceUriSchemesSupported to advertise the URI schemes it can accept.
 * The acceptable URI schemes are included as service attributes in the
 * lookup service; this lets clients search the
 * for printers that can get print data using a certain URI scheme. The
 * acceptable URI schemes can also be queried using the capability methods in
 * interface <code>PrintService</code>. However,
 * ReferenceUriSchemesSupported attributes are used solely for determining
 * acceptable URI schemes, they are never included in a doc's,
 * print request's, print job's, or print service's attribute set.
 * <P>
 * The Internet Assigned Numbers Authority maintains the
 * <A HREF="http://www.iana.org/assignments/uri-schemes.html">official
 * list of URI schemes</A>.
 * <p>
 * Class ReferenceUriSchemesSupported defines enumeration values for widely
 * used URI schemes. A printer that supports additional URI schemes
 * can define them in a subclass of class ReferenceUriSchemesSupported.
 * <P>
 * <B>IPP Compatibility:</B>  The category name returned by
 * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's
 * integer value is the IPP enum value.  The <code>toString()</code> method
 * returns the IPP string representation of the attribute value.
 * <P>
