I guess I missed an "or" as the statement should read:
: To install the native threads package, you need to first download
: the JDK, JRE, *or* RT and install that. Next, you need to get the matching
: native threads package and install that into the same location.
All you need to install is the JDK and JDK native package, *or* the
JRE and JRE native package, *or* the RT and RT native package.

Generally you only need one of them. The JDK is the "Java Developers Kit"
which includes the development tools, some demos, etc.
The JRE is the "Java Runtime Environment" which is the full Java Environment
including all of the international language support files.
The RT is the "Run Time" which is the Java Runtime which has the basic
set of files but none of the internationalization files.
The RT + i18n == JRE (i18n is available separately)
The JRE + tools == JDK (tools not available separately)
