With respect to the Oracle JDK, differences to OpenJDK RI builds (which 
again may be quite different from what you are building, per the above) 
would be things like additional documentation, executable 
installers/packages, third party materials such as bundled libraries, 
fonts, etc., deployment tooling, root certificates, commercial features, 
etc.

Some distributors provide their own versions of some of the above, which 
makes it hard to make a general statement about the differences between 
Oracle JDK and arbitrary OpenJDK builds. For example, OpenJDK builds by 
third parties are often provided as native packages on Linux by the 
respective third party distributors. In addition, things change over 
time. ;)

As such, your focus on that page to try to figure out the differences 
only for your own builds is a good restriction of scope.
