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.
