Don't worry. It quite common that: - the official specification of the standard is hard to read - most people prefer to read: - documentation for a specific implementation - third party tutorials My guess is that you did not learn Java from reading the JLS but instead read either the Java tutorial (from one particular Java vendor!) or bought a few books. :-) If that OpenJPA documentation is good then it will clearly explain what is standard and maybe provide a few implementation specific extras.
