OPENJPA-1932: Documentation update: remove Java 5 references (OpenJPA requires Java 6), remove sjvm setting from examples (no longer needed), improve formatting (we should remember to use literal/classname tags), fix typos.

The Java Persistence API (JPA) is a specification
The Java Persistence 2.0 API (JPA 2.0) is a specification
for the persistence of Java objects to any relational
datastore. JPA requires J2SE 1.5 (also referred to as "Java 5") or
higher, as it makes heavy use of new Java language features such as annotations
and generics. This document provides an overview of JPA. Unless
datastore. This document provides an overview of JPA 2.0. Unless
otherwise noted, the information presented applies to all JPA implementations.

This document is intended for developers who want to learn about JPA
in order to use it in their applications. It assumes that you have a strong
knowledge of object-oriented concepts and Java, including Java 5 annotations and
