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.

  * This exception is thrown to indicate that the operation reached
  * a point in the name where the operation cannot proceed any further.
  * When performing an operation on a composite name, a naming service
  * provider may reach a part of the name that does not belong to its
  * namespace.  At that point, it can construct a
  * CannotProceedException and then invoke methods provided by
  * javax.naming.spi.NamingManager (such as getContinuationContext())
  * to locate another provider to continue the operation.  If this is
  * not possible, this exception is raised to the caller of the
  * context operation.
  *<p>
  * If the program wants to handle this exception in particular, it
  * should catch CannotProceedException explicitly before attempting to
  * catch NamingException.
  *<p>
  * A CannotProceedException instance is not synchronized against concurrent
  * multithreaded access. Multiple threads trying to access and modify
  * CannotProceedException should lock the object.
